We had a very pleasant stay at Sylwia's apartment. Sylwia was very helpful prior to us arriving with information about getting access to the flat but otherwise left us to enjoy our time in New York. The flat is very spacious and comfortable and had everything we needed. The only downside is that the area was not very easy to navigate to from Jfk with no integrated transport information provided in JfK between NYC and Jersey City. If you stay here consider getting a taxi or travelling into Newark airport instead as you may find this simpler. Also there is a great pancake house on the way to the nearest Path station (Brownstone Diner) great for breakfast out.
