The owners are very nice people. I spoke to each of them on the phone. Both were kind and sweet on the phone. The place was nicely decorated with tasteful furnishings.
It's an old building in need of a renovation. We happened to be in NYC when it was very hot, and though the apartment has three air conditioning units, they didn't work very well. We were told that we could only run two at a time because the third would draw too much power and require us to venture into the basement to flip breakers. It turned out even running two of the AC units twice caused us to lose power and head to the basement to flip the breaker.
Other:
Slow wifi (We speedtested it at around 3mbps)
Tv didn't work at all. Couldn't turn it on.
Very limited closet space (mostly closet space was locked out of limits)
Even still, it's a nicely decorated and comfortable place and we enjoyed staying there.
