We stayed in the apartment for 3 weeks.The apartment was very clean and spacious for a studio although the kitchen and bathrooms are small (normal for New York). The kitchen is well equipped with nice fridge and freezer.
The apartment has a lot of cupboard space - hanging and shelves - which is very important when staying for a longer period. No need to live out of suitcases.
The apartment is at the back of the building, which makes it very quiet as far as the street noises are concerned. Like most older NY apartments it is not well isolated so you can hear the neighbors which could sometimes be very noisy, but mostly during the day.
There were a lot of problems with the heating and gas, but is was out of the control of the hosts and they did everything to help remedy the situation. They warned us a couple of days before our trip that the gas pipe to the building was broken and they will have to provide a space heater and cooktop, but we could cancel if we wanted to. Unfortunately cancelling was not an option since it was too late to find something for the same price for 3 weeks. The heating was fixed during the first week, but the cooking gas was never restored and the there was no gas for the dryer in the basement either, so we had to have our laundry done elsewhere. The boiler in the building also had a problem while we were there and they had to come and fix it.
Again, none of this was the host's fault and they gave us a partial refund for all the inconvenience.
This is a nice location to stay and not far from the subway. With the new 2nd Ave subway line opening soon it will be even closer. Large choice of good restaurants in the area.
We will definitely stay in this apartment again - as long as the gas has been fully restored.
