It's a cozy, small apartment next to the critical 6 line which you will use everyday. The room is filled with stuff (a bit too much of it) but it's just a slight inconvenience.
Internet is good for working and anything else, really. It's quiet and the shower works properly (for the most part).
Go with this is you're looking for a place to crash after long days. The fast pace of New York will really keep you occupied and you won't think twice about the few "inconveniences" of this place.
