The experience we had in Kieran's place is beyond words!
It would be simple to just RAVE about the central location... You have the opportunity to take advantage of the best of historic Philadelphia, while being just as close to taking either taking advantage of the liveliness of South Street OR strolling down to Penn's Landing and enjoying Harbor Park.
However, simply focusing on the location would undermine the accolades the apartment deserves. The space is deceptively large -- with a spare room space that allows you to feel free to breathe in the space. The bedroom is large and open with an extremely comfortable bed, and the living room sits two large "love seats" that allow people to sit without feeling crowded... On top of that, the windows open up to a great view of Historic Philadelphia (side note: we were able to watch the fireworks show on the Riverfront from a love seat drinking a glass of wine).
While we thoroughly enjoyed everything about the space, there are two things another AirBNB'er should keep in mind...
First... The space is on the 4th floor, and you will need to navigate stairs. While this was something that was fine with me, I could see some travelers seeing this as a challenge. Additionally, it was a concern of mine that we were creating noise while taking in items for our stay, because of taking items up the steps.
Second... The water does take a little bit to warm up. Once it does however, it has GREAT staying power -- as we never lost hot water.
Bottom line, Kieran's place is HIGHLY recommended by both of us. It is actually our hope that we were deserving enough guests for how wonderful the space was.
