We stayed with 7 people (4 adults and 3 child) for 3 nights in the apparment. It was enough space for all of us,(2bedrooms for the adults and 3 places for the children in the living room). The rooms were clean and tidy, but the AC in one of the bedrooms was leaking, We turned it off because there was still a lot of water on the floor.
The stairs to the flats are plenty and small. So it was a hard work to carry our luggage over the narrow stairs to the apartment on the second floor. We had to cross the kitchen of the underlying studio which was a little bit strange for us. Especial because the renter of this studio had to cross this kitchen also to arrived his shower and his restroom)
East Village isn't a calm place for sure but absolutely perfect for exploring Manhattan. There is hustle and bustle in the streets by night, so you have always noises around. But you will be able to sleep in because the street is very quite in the morning.

The communication with Keith was ok. The instructions for getting the keys was clear and the responce of our email in time..

All in all: If you want a not-to-expensive place, very close to Mannhatten.Keith's apartment is the right choice.
