Very nice hotel with good city views. The downside for me was the ppl talking in the corridor at midnight. We were given a room on the 25th floor. Need to use hotel room card to ride the elevators up to this level 'cause it is one flight below the "Club Level" which led me thought it would be quiet at night 'cause few people would have access here. But I was wrong. Around 2AM the corridor suddenly became filled with people walking talking like a party was going on. Not sure what's going on and how that happened. Would have given a 5-star rating if not because of that.
