I haven't met Alex but Rez that is renting out the other room. He was very welcoming, helpful and kind. Alex checked in on us very regularly; but being in NYC we couldn't even always find the time to answer.
The location is great, only a few blocks away from subway train 6 and has a bus stop right in front. Due to the doorman, you feel really safe in the building as well as the area itself. Shops are around the corner. The view from the rooftop (and out of the bedroom) are phenomenal. My fiancé and I stayed for 10 nights and really recommend this place.
