MaryRating, 5 stars3 weeks ago
The apartment is beautifully designed, spacious, relaxing, and comfortable. What more could you ask for? We enjoyed our 3-night stay. Read some of the assembled books on birds and enjoyed delicious food at the local restaurants. Alice was a gracious and responsive host. You will truly love staying in her apartment!

This place was great and very clean. This is an Airbnb that beats a hotel every time. Close to Acadia, and has river access. Very nice place, and I definitely recommend staying here. Everything was high quality from the furniture to the silverware. Thanks again!

Duck Cove Apartment

KariRating, 5 stars6 days ago
The apartment was perfect for a couple. It was clean and had all amenities we needed. The views of the water from the living room were nice and sitting on the deck with coffee or a cocktail was perfect! The seats by the water made you feel like you were away from everything. The hosts were very kind.

Cottrill House on Damariscotta River # 1

MaddieRating, 5 stars3 days ago
We absolutely loved our stay here! The location was perfect, right in town and right by the water. Lissette was very attentive, gave us a coupon for the place we were going to dinner in town, and then we mentioned we were wanting to do a bonfire and she started it for us! We loved sitting on the private dock and enjoying the river views and being able to walk to get breakfast, lunch, or dinner in town. Highly recommend staying here!

Waterfront Condo at the Sheepscot

TeddiRating, 5 stars5 days ago
We had a lovely night at Audray’s place! The location & the views exceed expectations. It was clean, cozy and inviting. Edited to add- not reducing stars for this because we enjoyed the accommodations, but I want other travelers w/ pets to be aware: Audray reached out 24+ hours after we checked out to say her cleaning person reported “an excess of pet hair on furniture and linens than her washing machine could not handle”, and requested we mail her an extra $50 to cover special laundering. We sent $75 on platform instead as we were shocked and sorry to hear this. We found it surprising b/c were in the condo only 14 hours, we immediately covered the furniture w/ pet covers (we brought our own) upon arrival, we covered the beds w/ our own extra top sheets to protect the quilts from pet hair, & we do not let dogs sleep in the beds- we bring pet beds. We have only received compliments on cleanliness & exclusively 5 star reviews from hosts over 7 yrs and 23 stays all w/ multiple pets.

Cove House

SusanRating, 5 stars8 months ago
We have been going to this area of Maine for over fifty years. I found this gem several years ago and haven’t stayed anywhere since. I find it to be peaceful, walkable to the center via footbridge, it’s all that we want. Kathy is a great host, quickly responds to any questions or needs you may have. We always know we will have a great experience staying here.

Water's Edge-Oceanfront with Stellar View

AmyRating, 5 stars1 month ago
Gorgeous ocean views right on the water! Every room has gorgeous photography on the walls, the house was extremely clean, everything clearly laid out in the house manual. Sunrises and moonrises over the ocean were stunning and unbelievable. Amazing location, super close to Tidal Falls. Drive to Acadia was easy and it is a great spot in between the Schoodic peninsula part of Acadia and the Bar Harbor part.

Cozy Waterfront Home With Breathtaking Views!!!

JessicaRating, 5 stars1 week ago
We had an amazing time. TJ was very responsive and gave his secrets for fishing! He also accommodated a request that was an overlook on my part. I can’t say enough good things about the place itself or how nice TJ was. It was a phenomenal experience all around!

Renovated home with amazing waterfront views

NicoleRating, 5 stars1 month ago
Thoroughly enjoyed our stay! We unexpectedly had beautiful cloudless days most of the week. Great location & easy to get to the Harbor and Southport both of which we enjoyed! Recommend the Carriage House for a really top quality meal as well as Blue Moon Cafe (good lobster roll) which was one of Shirin’s recommendations. Would totally stay here again!!

Summer River Retreat with Hiking Trails

RobertRating, 5 stars1 week ago
Everything was as described! Very tranquil setting. Loved sitting on both the sunporch and deck watching the boats go by. The house was immaculate and very well equipped. NIce to relax without the distraction of tv for a change. Enjoyed their Bose radio.. Also the verizon phone /computer connection was excellent. It was a great home base for exploring the mid coast of Maine. Lots of good restaurants near by and the owner offered many heloful hints as to what to see, where to est and what to do. His communication was excellent. Would highly recommend this rental.

Riverside

MarleneRating, 5 stars3 weeks ago
This was my 5th time going there and I love it! The house is so cozy & very clean. The property is large and the view is breathtaking over looking the river. They are also pet friendly so we were able to take our Lhasa Apso Revy on vacation with us. Besides how great this Air BnB is, my favorite is the hosts Kent & Tish! They are wonderful people. They are kind & friendly, & have such beautiful souls. They have become family to me! I highly recommend getting this air bnb!! Thank you again Tish & Kent! Ian, Revy, & I are always happy to see you!!

Lakefront: Private Hot Tub, Sauna & Free Massages!

MichelleRating, 5 stars5 days ago
We had two nights to spend in Maine after a week long trip to Quebec. The lake house was a wonderful place to unwind after our busy trip to Canada. We spent our full day parked in the yard, enjoying the boats provided, reading, playing bags, and just sunning. It was a gorgeous day, and we loved it. The house is spacious, very well-stocked, and has many little amenities to make it feel like home. Highly recommend!

Charming, newly remodeled space atop Munjoy Hill.

ChrisRating, 5 stars7 months ago
Unit was very clean, situated in a quiet residential area and within walking distance to many of Portland's best bars, restaurants and attractions. Host was communicative and provided clear guidance on check-in/-out procedures and offered up suggestions to local attractions. On my recommended list - dinner at Twelve (one of the best restaurants in the US, IMHO); on-site food truck tacos washed down with a Hazy IPA at Bellflower or Austin Street Brewery; an everything bagel with lox & morning latte at Forage; the East Promenade for a food truck lunch, then a stroll along the waterfront trail to the port area for an ice cream cone at Gorgeous gelato; afternoon coffee at Double Great Coffee; and a post-dinner whiskey @ Independence Ice. Only downside on my visit was the upstairs neighbor. Dude clearly isn't a principal dancer in the Portland Ballet, as light on his feet wouldn't describe him. Not a stereo or TV issue - you can just hear the noise from him walking (8AM-10PM when there)

Toddy Haven: A Lakeside Condo Near Acadia.

KenRating, 5 stars5 days ago
We rented both the Toddy House and Rocky House for a week for our family of 12. The houses were as described and in pristine condition. We loved the fact that they were close together, so the late night group could stay up socializing, while the children could be put to bed without distraction. The Toddy House had a pool table which provided lots of late night entertainment. It also had a large open common area to accommodate our group, and we spent a lot of time on the screened porches. We really liked the access to the water with the dock, the canoes and kayaks, and the super cool fire ring. We are the type of family that asks a lot of questions, and Mark was quick to answer and take care of any questions or issues we had. We spent a great deal of time at Acadia, and while the drive was about 45 minutes to get there, it was not a problem at all. We would definitely return to 3Havens if we decided to take another vacation in this area. Mark and Laurie were excellent hosts.

Harbor View Cottage Unit A 2 bedroom downtown

BrandonRating, 5 stars9 months ago
What a beautiful location and house. There’s nothing better than sitting in the living room or front porch and being able to see the Belfast Bay. The house is very clean and neat. Beds are comfortable, shower is very hot. Don’t miss the sunrise in the mornings. Overall this is one of our favorite places we have stayed in Belfast.
