We (a family of four) had a wonderful stay at Sabrina's. The appartment is very clean and comfortable and very beautiful decorated. A nice place to relax during your stay in New York. Sabrina's house is also very conveniently close to a stop of the L train, which leads directly to Manhattan. In 10 minutes you're standing on Union Square.
Sabrina is a wonderful host. She gives a lot of tips and addresses of things to do in NY, and is very helpful, even when she isn't around. Although we didn't meet her, it is all very personal. It felt like visiting the appartment of an old friend. Highly recommended!
