Not bad, very accommodating reception staff. They easily changed our room from smoking to non-smoking . We got a better room and higher floor (14th).
The only thing that bothered me throughout our 4-night stay was the concert on Fremont Street below. It was like listening to a radio that you cannot shut it off. I love the 80's music...didn't mind that but when I want to sleep before 12am that bothered me a bit.
Overall, the place was Ok.
