We stayed for close to a month and loved it. The bed is comfortable, the apartment is beautiful and gets really lovely light throughout the day. We cook quite a bit so adored his gourmet kitchen which is set with everything you could ever need (really). VERY quiet building, though as other reviews have said, many flights of stairs (normal for NYC though and the building is quite nice). The bathroom is large and the finishes are modern and nice (towel warmer, etc). Of course you can't beat the neighborhood and access to public transit. Right across the street from a cute little park as well.

Lenny himself was a pleasure to work with and was very respectful when he needed to grab something from the apartment. Very responsive and accommodated our unusual check in and out times. Would recommend to anyone looking for a great apartment
