We are the family of four (parents and two adolescent daughters) who were visiting the NY and stayed for 8 nights at Gary's place. During our stay everything was perfect - the flat was spotlessly clean, there was enough place for everything (enough wardrobes etc.), Gary left us some food and refreshments in the fridge and cupboards, which meant a lot after long transatlantic trip. He waited for us to introduce us to the flat and to explain us everything, and he was always there and easy to reach by phone when we needed him.
The flat is at very convenient location - it's quite easy to reach Manhattan or any other part of NY, including JFK airport. And the neighborhood is safe and quiet, as well.
We visited a lot of standard tourist places and quite a lot of non-standard ones, and were happy to find out that all of them are within easy reach. In the vicinity of metro entrances (lines 2, 5 (slow ones) and Q (a quick one) there are enough shops to buy food on the way back from Manhattan.
So, all in all, the flat and its location is much more than we expected it to be, and Gary and Sylvia are wonderful hosts and we highly recommend them without any reservation!
