This was the perfect place and location for us. We are a couple, one of us attending a conference at Columbia half the stay and the rest we spent enjoying NYC together.
Juan is the most welcoming and attentive host you can imagine. He strives to accommodate and succeeds (both counts).
The apartment is cozy, clean and quiet and very nice if you like to experience how it is to live in NYC upper west side (which is what airbnb is about, I think). Does not take much AC to cool down either. Windows to the back yard, which gives plenty daylight but no direct sunlight.
Location is great. 2-3 min to subway. City bikes the same. Several delis, grocery stores, and restaurants two streets up, so supplies (and take away) was never an issue. 20 min walk to Columbia. And Central Park, oh the park, worth several visits and right outside the door.
We had the best of stays here!
