We picked this place because of the location and because it looked well decorated.
It is pretty small for 4 adults and a 20-month-old baby.
The worst part was the heater. We had no control over the temperature. Most of the time, the radiator was extremely hot. It's also pretty loud. We had to keep the windows opened at all time. On our second night, we had no heater at all, no warm water. End of March, outside temperature was 38°F. Fabiana told us there wasn't much to do about it since it was an old building. Fortunately, someone eventually made it work.
The sliding windows don't slide properly, are tough to open and there is no way to lock them securely when you leave the apartment for the day.
Wifi is extremely slow. Mail is ok. Social networks kind of ok but forget about streaming a TV show. We also tried several times to watch TV using the Roku box but the TV kept displaying the same error message: HDCP Unauthorised Content Disabled.
Note also that the street and the neighbors can be loud at night. It is a very old building with no sound insulation. I guess it's common in New York but keep that in mind if you are a light sleeper.
