Very clean, nicely decorated, only two mins walk from Tivoli, 10 mins walk to the trendy bars and restaurants in the Meatpacking district. Lidl is just round the corner to stock up on groceries.
There is one separate bedroom and two pull out sofa beds in the living/dining area. There were four of us which was fine, perhaps six people would be too cramped, but that's just my opinion, this would be fine for many people.
I would definitely stay here again and would highly recommend it.
