I stayed 10 nights alone at Annie's home on a business trip to NYC. First and foremost, Annie had been an incredible host. Very responsive and helpful. Perfect and easy checkin and checkout. Even though she was traveling during my stay and we had long time zone differences, she was always there to help if I have any questions. Second, the location of the house was amazing. I stay in NYC at least twice a year and I can tell that this was one of the best location that I stayed so far. Thirdly, the house was clean, minimalistic, modern which is important for me.
Two very minor considerations might be:
1) the size of the bed. It is a full size bed (which she mentions already in the profile) For a solo traveller like me, so it is more than enough for one person. But if you are traveling as a group, that might be something to keep in mind.
2) The apartment is on the 5th floor (as she also mentions in the profile) I didn't mind climbing the stairs but just keep in mind, might be challenging if you have too many luggages.
