This hotel is so small that you can walk right by it. The creation of it is an amazing feat of engineering. The width must be no more then forty feet across yet they manage about six rooms per floor. The total rooms must be only about 40-45. A hotel like this can only be found in the US in New York but in Europe's big cities it is more common. The lack of space requires numerous compromises that you won't find by larger locations, no closet, desk, or virtually any space to move in your room. Your bed will take up 80% of the room and the TV console will take up another 10%.I found it humorous how the bathroom door brushed by the toilet when you opened and closed it, they measured this puppy down to the inch.
I found as a solo business traveller with only minimal interest in hanging out in my room for this to be a perfect hotel. The location is as good as it gets with the St. Regis just down the road going for 800-1,000 a night. You get to pay as much as a chain hotel and get a boutique feel and personal treatment from the staff. My meetings were two blocks away and I was within a couple of blocks of some great eateries and an evening run in Central Park.
The negatives are that these rooms work best for solo travellers. I wouldn't want to share this room with anybody. In addition if you get a room facing 55th then you will get a lot of noise coming through the windows until 11 and starting up again around 5. The curtains are also curious in that they don't block out the entire light which also causes you to wake up earlier then you perhaps would like.
Overall for the solo and at most couple travelling who want to spend most of their time running about the city and just need a convenient place to sleep after a busy day of exertions, you really have a great option with this hotel.
