Do not stay for business, awful internet connection and very loud.
I stayed here for two weeks, and the concierge commented at checkin that that was weird, because this is very much a party hotel. Being right of 6th street, which is party central, most of the people who stay here are tourists or wedding parties or short term business conference types. Of course, if you're looking for a party, it's the place to be.
Downsides for me, as I was staying for business were;
-Incredibly slow, unreliable internet connection.
-Limited room service menu / restaurant has the same food. Mostly burgers and pizzas. It's nice, but boring after two weeks.
-Thin walls and drunk clientele. Both of the weekends I was here I was woken up either by enthusiastic couples (use your imagination) or drunken people on their way to / in their rooms. It's only quiet Mon-Wed really. 
Positives;
-Lovely big room, clean and comfortable.
-Great location, for touristy and party stuff
-Good service whenever I rang or when I had a noise complaint (that enthusiastic couple were noisey for several hours)
Essentially, if you need to work / eat / rest up for work and are doing a long stay, everyone so far has recommended the W instead. But if it's a short stay, or you wanna party, and you want something slightly high class, it's a good place.
