The location is just amazing. You are very good connected and especially, If you like to see all the museums like Guggenheim, the mets, etc. you can find them just some blocks away. The place is also very clean and neat.
Just If you are a light sleeper, be aware that you can hear everything the other guests do. The flat is very claireaudient. You might will awake in the middle of the night just because other guests are watching TV or making a phone call. If you mind to not be able to sleep trough, I would recommend to book one of the "real" rooms in the apartment.
