1) If you have big suitcases like me (I had two), I don't recommend this house because you will need to carry two suitcases to floor 6 all by yourselves. (The host couple were out of town when I check in, so I spent half an hour to bring my two suitcases to floor 6).
2) However the location is really great!!! Very close to all sightseeing attractions in Manhattan, very close to two subway station. Great place if you wanna see more of Manhattan.
3) the bedroom is super super small, much smaller than I expected. I hardly find room to have my suitcases fit in the bedroom. The smallest bedroom I have lived in for sure.
4) the wifi they provide has low signal... for the five nights I stayed there I was all using my data package. The host did tell me she ordered a new wifi receiver or something, but I didn't see improvements.
5) With those being said, in general the host couple are quite nice and friendly, I do feel welcomed there.
