We just stayed here for four nights. Sadly, they no longer have a pool on the roof. If you check out the Trip Advisor reviews, you'll find that some of them mention the smell of mold in some rooms, and other reviews are absolutely stellar. Unfortunately, we got a really odd smelling room on the 21st floor (2107, I think). And we had to yank really hard on the door to get it to close.
My BF brought this up to the front desk, and they said they'd look into it, which reads, "we'll do nothing". We wanted to have some people over but the room just smelled too damn weird and so that never happened. The issues weren't dealt with at all, and that makes me sad, because Marriotts are usually pretty good. At least the free breakfast was okay. Having free coffee and tea and breakfast is a nice way for cash-strapped travelers to save some money.
