We stayed at Yulia's place on the upper west side for two weeks.
It was absolutely GREAT!
The neighborhood is my favorite and the apartment was right in the middle of everything yet very quite.
The building is well maintained, clean and nice, with laundry in the basement.
The apartment has everything you need to make yourself feel like home. Huge bed, big bath, and great living room.
Yulia was available for any question and was very responsive.
Overall, this is definitely the best best I've stayed so fat in the big city and I truly hope to return .
