We stayed in Joanne's Apartment for 3 nights. Check in was super easy, she couldn't be there to welcome us, but gave us very good instructions to find the apartment and regularly checked if everything was okay with us. Her Dad let us into the flat and gave detailed and friendly information about everything we needed to know about the room and also about the subway station next door.

The room: comfy bed, everything clean, more than enough space for our stuff. A hair dryer was provided (or at least stored so openly that I assumed I could use it). Bathroom was also clean. Enough towels for both of us.
It was kind of loud, but I guess this has to be expected when staying in New York. With ear plugs, sleeping was no problem.

Overall: if we go back to New York another time, we will definitely try to stay with Joanne again :)
