I'm going to give this a 5 star, with some reservations. Positives with unit: The place is nice, central location, bed is comfortable, good amounts of space, etc. Little to no trouble with street noise. Wifi/Internet was very strong. Negatives with unit: HVAC unit is really loud, neighbors get loud at times (not the unit's fault, obviously) and you will not be given a key to the outside door. So, you just have to have the doorman buzz you in every time, or tailgate in with someone else. I never waited more than three minutes, but I definitely waited once or twice.
The "process" had more than a few hiccups. Notably, the unit had not been cleaned, at all, when I arrived. OK, mistakes happen, but it was pretty frustrating because I had already been hanging out in the city waiting for the strict check-in time, and been carefully complying with all the other rules. Then, I basically had to get kicked out again. There was also a broken piece of furniture. To their credit, they handled both of these things very promptly and, for that reason, I'm throwing a 5 star at it, because they were communicative and responded quickly. The unit is nice, with some room for improvement on the "processes."
