We stayed for 4 nights only but would totally recommend it to anyone.
The pros:
1. Very friendly atmosphere (we spent some nights just talking to Min) and some good and useful sightseeing advice.
2. V. good location (just few stops from Manhattan and the subway itself is like 5 min away).
3. The Dog :-) Even if you are not the "doglover" type Schatzi is the most adorable dog ever.
4. If you are lucky you can taste some of delicious food Min is preparing.
5. The room is quite comfy & has enough space (although the window is a bit leaky).

Cons:
1. If you are by car then it is quite problematic to find a parking space - usually you will have to leave the car quite far from the apartment. But that's an overall problem in NY.
