The host was great. He checked in with us to ask how we were doing and to give us suggestions about where to to and to eat everyday. We really appreciate it. The flat was nice and very well located.
Two things worries to be mentioned.
1) we would have liked to have a little bit of more space to move around as the flat was completely full of things.
2) we found a lot of dust in several ítems around the Flat.
Summing up, adjusting these two things, I would definitively recomend Matthew's place for a quiet stay in NYC.
