4 star really?
I am currently living in this hotel. Stay here for two nights, one more night to go. I am in architectural profession, so I have lots to say. Good things first, clean, and staffs are nice, at least at the reception desk. So I gave one point to this, and plus the location is very good. The other point for the public space, where are the lobby, library.
Bad things, the room is tiny, but that is not an excuse. Using brown color wood panels to cover the wall, which is bad decision, it made the room dark, and the material just so cheap! It feels like painted plywood. No Ectrical outlet on the wall, only an extension cable, which you need to unplug some devices from the room. The bed, clean, but they use three linen sheets, two sandwiches the blanket, one cover the mattress. That is normal, however, when you get in your bed, you mess up with those sheets, then you can see the mattress is not looked kind of old,which is not good at all.tv screen, is too small, and not at good location, even it has supporter can turn the angle, but just a little bit. The hair dryer, it's the cheapest one you can find at a dollar shop probably. It's a four star hotel! Ladies would hold on that for a long while. What is cost for a good wall mounted hair dryer?! Bathtub, not a good idea to put bathtub in such a small room. If you want take a hot shower and relax, who would want to use a bathtub, which you even can't stretch your legs? And plus, the tub is white, that is good, but, if you want to sit into the tub, you would not want the tub with the sandblasted texture, cuz, it doesn't feel clean. Air conditioning, there is reason that why you need an architect to design your building. If you don't think good enough, like here, they put the heat venting right behind your bed. It makes a lot of noise! Common sense, come on! 
This is the first time I visit NY, I don't know what is the standard for a four star hotel, this one is not in my mind. Costumer service, details, this is what makes people spread the business for you,a room like this, sorry, I'm pissed! Unpleasant. This is New York! For Christ sake! I'm not in china! You telling me you will charge me 512kb wireless connection for 10 bucks a day! You out of your mind? I spent the money for services, good service, not a fancy lobby, and a location. Let me know, if the Hudson needs ideas, I will be your consultant.
