It’s so clean and shiny and new. The service wasn’t as excellent as I expected. I stayed 3 night and my room wasn’t serviced at all in those days. That was disappointing. Also, a couple of the bell greeters were not very nice.

Everything was great except the check in . We arrived a little early and was told we would get a text when our room was available . We never got the text and when we went back to the check in desk on the club level 4 hours later , we were told that sometimes the text does not work ? ? ?
