Location is unbeatable - literally all the conveniences one can expect within a few minute's walk. Even though the apartment is on a very busy street, the noise level within the unit is very minor (there was a construction going on across the street and we were worried since we'll be working during the day, but it turned out to be a non issue.) The building is clean and well maintained, minimal decor and you'll have all the basics you'll need.
One note of caution -- bring your keys everywhere and do not lock yourself out. We made that mistake and nobody was available to assist us because we arrived on a Sunday night around 9pm. We ended up having to check into a nearby hotel our first night because phones/emails/texts all went unanswered. For clarity: We received two identical keycards and assumed we had two cards because we registered two guests in the room. The check in instructions we received talked about a key fob for the building entrance so we left the apartment with just one of the keys and went looking for the key fob. Turns out one keycard was for the building and one is for the apartment unit, and there were no keyfobs, so we got locked out of the apartment. Someone contacted us first thing on Monday morning but can't imagine what we would do had we not have a phone and wallet on us.
All in all we did enjoy our two weeks stay and would highly recommend this place if you're visiting NYC.
