Just back from a long weekend in NYC at Julias place. The flat is super nice, spotlessly clean, quiet + very spacious (rare for NYC!) and has everything that you would need. The building itself is very typical New York loft style, and the location is exceptional - in the middle of Manhattan - so everything is easy and quick to get to!
Our interactions with Julia were really easy. She is responsive on-line and very welcoming in person, and even let us check out late so that we could spend the day roaming the city before our night flight (thanks J!).
All in all a great place to stay in the city, and a great host!
