Mike is a very welcoming and helpful host. The room itself is very small and you don't have that much for luggage. But because you can use a big shared livingroom and the kitchen, that's not a big problem. You can get to times square in about ten minutes, so the location is great to start discovering NYC. But it's not really quiet at night.
The rooftop has a good view and is very nice, but only accessible by ladder.
It's a good appartement to spend the nights but during the day, I'd recommend to visit the city.
