I stayed here with a friend, with one of us sleeping in the bedroom and one on the couch. The place was perfect for us. Check-in is a breeze - grab the keys from a 24/7 accessible lockbox around the corner, the place is clean, the apartment is really quiet despite being in a neighborhood that isn't, tons of food, drink and things to do and see within walking distance, and it's super close to the F train if you want to see more of the city.
The apartment is small, as is typically the case in Manhattan. If you're planning on spending a lot of time in the apartment it's probably not great (but if you're planning on spending a lot of time in the apartment, maybe don't go to New York because you're doing it wrong). The bedroom is windowless and gets nice and dark. The bed is really comfortable. The pull out couch get the advantage of the window AC but does get a lot of sun. I'm told the pull out couch is perfectly comfortable, but if you're over 6 feet, you'll want to be diagonal on that bed.
Water pressure is good, shower is hot, place is clean, and Mariana couldn't be better about communication. Would absolutely recommend.
