First I must say that Barrett would respond in most cases almost immediate, in the worst case about 10 minutes. The pick up of the keys was easy and the drop off even easier. There is a living room and a little table next to the kitchen. The bed is located in a small alcove apart from the living room and at a pace away from the bathroom. Toilet has a nifty bidet. There is air conditioning which works and came in handy for the 2 days which where 90 degrees. If you are into books with photos you are in luck.
The area (East Village) is wonderful, meaning that there are several places to pick from within a 4 block radius for food, coffee, bagels, and just about anything else you need.
We stayed for 5 nights and were able to walk the 3 floors up, we are pushing 60, hence 59 and 58. The cleanliness is livable, and really it is only in the bathroom which seems to be true for most places in NYC at this price range (cramped bathroom, several steps to climb and tiny-Barrett's place was not tiny).
You do have access to the roof as Barrett let us now. The closest subway station is about 3 blocks away.
Felt safe.
