Nadir's place is 100% recommendable to sgtay in NYC. The location is great, in a quiet neighbourhood, very close to the 30Av subway station in the N-W subway line. The place is quite comfy. The room is decently sized and the bed very comfortable. The bathroom is shared but it is clean. You have access to the kitchen (quite useful in a expensive city as NYC) and living room. The communication with Nadir was very easy and he was very helpful despite being away on holidays.
The only downside was the noise generated by the building heater installed on the room. However we get used to it after the first night and was not a problem. Also you can close the valve on it and use an electric one available on the room, so it should not represent an issue.
Many thanks for all Nadir!
