Charming use of limited space
What a great idea. Cram a shedload of tiny "cabin" like rooms and hallways in a hotel. So NY. 
The single cabin makes very good use of space. I would have been thrilled with it, but for the "bed" which really isn't one. It's a small mattress plunked on top of a wooden plank. I woke up continually throughout the 1st night, missing my latex mattress at home. 
There was also a half-eaten snack bar in the room when I arrived, so the cleaner wasn't quite thorough enough, although they seem to be great about the shared bathrooms. Which are unisex, by the way, if that bothers you. The only thing that bothered me were other travelers seeming to expect to have a chat or something. I'm brushing my teeth ffs. 
The Parisian cafe attached is nice. The avocado toast is everything the reviews here and on Yelp said it would be. 
The location of the hotel is v. good.
