We were a family of six meeting in New York. There was plenty of room and all the beds were comfortable. The house is a lovely older home and quite charming. That means expect a few quirks and follow the guidelines from the owner. The kitchen was well equipped for basic meals (but with so many fantastic places to eat within blocks we really didn't cook). Elle was very responsive for any questions.
The neighborhood was ideal for getting a feel for life in the city. Not a touristy area, possibly because of the distance from Manhattan, but for us that was part of the charm, and affordability. We used an unlimited subway pass and easily got to all the tourist sites. For the teenagers it was a great experience for life in a major city and using public transportation. We had breakfast in local diners, and tried various places for dinner, German, pizza, Italian, Turkish. We only had one dinner in Manhattan in Chinatown.
