Our stay at Ryan's was just perfect. He was incredibly helpful answering all of our questions about things to do in NYC, esp. with a 6-years old. He then was totally reactive during our stay about technical questions.
The apartment was really pleasant: very bright, with 2 bedrooms upstairs for the 5 of us and a large living room downstairs. It is located just 15 minutes walk+subway from Union Square - so absolutely convenient for all sorts of things. And the tips that Ryan gave about the local area (small shops or places to eat) were much appreciated. Just perfect !
