To sum this place up in one word, I'd have to say "Interesting."
The decor is great. Very artsy and colorful. But some things are definitely out of place, and the designer definitely had some kind of foot fetish. I'll leave it at that.
Note: I did not stay here. So I can't comment on the rooms or stay, but I did gamble and eat/drink here and that was a very positive experience. Their restaurants are definitely up there, and their bartenders were all super approachable. One even made me a champagne cocktail because he heard me say, "I 'm craving a champagne cocktail but I don't see any on the menu." That's awesome.
My only complaint, the place is totally confusing to walk through. It has about 3 or 4 floors and they're all split in different directions and what not. Not really "user friendly" if that makes any sense. But apparently these were supposed to be condos before the decision was made to make the Cosmo so that explains it a bit.
Definitely worth checking out.
