I'll start with the less-than-great details about the apt. (most of which are out of the host's control). As others stated, the room facing Avenue A were loud, especially on weekend nights. We had earplugs and most of us managed until Saturday night, which happened to fall during "Santacon". The noise wasn't only creeping in from the streets but also the apartments above, beside and below. Our neighbors partied hard until 4 am and none of us could sleep. For the most part, the place was clean, but it looked like only the high spots were hit before our arrival.
The good: This place is a GREAT location if you want to hang around East Village or hop over to Chinatown. Midtown is a short subway ride away (after a short walk to the station). Additionally, the price point was great and everyone in our party could hang comfortably in the flat while together. The beds were comfy, and Kadriya was responsive and most helpful.
