The 350 rooms are small(ish), at around 17 sqm, but seem larger, partly because of the floor-to-ceiling windows and partly because of the design which makes the most of the space that there is.
There are hangers along the wall opposite the bed (rather than wardrobes), storage space under the bed (including the laptop-sized safe) and the narrow washbasin in the corridor as you enter the room opposite the separate toilet and good-sized shower. There were a couple of small bottles of water for sale on the basin ($5 each), but if you have a refillable bottle (and you should have!) there is a place to fill it in the basement fitness centre.
The dispensers for toiletries in the shower are on the wall, good for the environment, if difficult to extract anything from, but there is no separate bin for recycling.
There’s a full length mirror by the door, the bed is very comfortable, and there is a small work desk which folds down from the wall and a collapsible chair (when you arrive it is hanging on the wall – I thought it was the luggage rack at first). I don’t think you’d want to work at the table sitting on that chair for long, and if I had done so I would have required medical help to leave the room, but the table is a good place to store and charge things, and there are also charging points all around the room including both USB docks and US main sockets on both sides of the double bed.
There are limited number of room types with standard rooms being on floors 4-21 and then those with a city view being on 22-32. Note that one side of the building faces towards the Empire State Building, and so you want (if available) to have one of those on one of the higher floors, though there aren’t many of them.
There are 226 King rooms (17.7 sqm), and then a further five of these are King View; Double rooms are 18 sqm and there are 95 of these, with just a further five Double Views. Some rooms allow for four to stay – these are called a Quad Bunk and there are 17 of these. Then there is the Mondo Suite which is 70 sqm without bedrooms (when you would use it as an event space), or can be used with one or two adjoining King bedrooms.
The best rooms are higher up the building and on one side these have outstanding views of the Empire State Building. In fact, this view is one of the best I have ever experienced in over 50 visits to New York. Yes, you can stay south of Central Park, but the price for that view would be four times as much.
I spent a lot of time taking pictures of the view, not least when a praying mantis came to visit and watch me through the window. I wasted an hour or so videoing it, but to be fair, it seemed just as interested in me. It was also fun watching it climb up and down the Empire State Building, though instead of Godzilla it was more like the insect in the Edgar Allen Poe story, The Sphinx (interestingly written at a time of contagion – cholera – and set just north of New Rok in a house overlooking the Hudson.)
