Do you know when people explains that they found a place through airbnb that was insane, and great, and unique, and you just find super touristy impersonal apartments even though you look everywhere?? So this is what your friend found, and what you are looking for. This house... man.. Is beautiful, suuper comfortable, well thought for having the best time with friends, warm, ... I can not recommend it enough.
As for practical information, there are 3 private beautiful bedrooms with natural light, one big extra bedroom in the basement (with toilet and everything you need) and the possibility to add a bed in the corner of the living room, which is so big you would not even notice. We used them all and an inflatable extra mattress and there was plenty of room in the common areas. As for the location, is south Harlem, which is not a touristy area but the area is nice, and there are plenty of groceries and liquor stores and everything you may need nearby. And 2 metro stations at 5 minutes walking, one to the line 1 and the other for A, C, and B, D lines. Both go straight to the midtown and downtown. What else... I don't know. Just check out the photos and if you like what you see, there you will find what you expect, but better. So far, my best airbnb experience.
