This is a beautiful bungalow located 10 minutes walk (or a 2-4 soles moto taxi ride) outside of Mancora. The bungalow is on a private lot with only one other cabin so it feels very private. There is an empty beach directly out front, although the view is blocked by a wall. The bungalow has a mini fridge , coffee maker, and microwave.
I stayed here with only one friend but there are bunk beds, and the space would be big enough to comfortably sleep 4 people.
I didn't interact much with Guillermo but he responded immediately to my inquiry and left me the phone number for his brother, so I felt like I could reach the hosts at any time.
The only problem I had was with the mosquitos- it had been very rainy in Mancora and there are bushes around the house, so at night the mosquitoes came out. Not a big issue, I would just recommend bringing repellant for a stay here!
Overall we had a wonderful time and I would highly recommend this place!
