Poor front of house service/staff
I just stayed at the Andaz for two days in July 2012. I called the day before to confirm my reservation and was told that check in time was 3pm. I arrived at the hotel at 2:30 and was told by the man behind in the lobby that "a room was just being cleaned now" and asked for my phone number to call me when it was ready. I was not feeling well and he assured me that it would not be long so I went to sit in the lounge on the second floor. 
After about 50 minutes I went back down to ask what was happening, and he said "oh nothing popped up on my system as being ready yet" even though he had said he would call housekeeping and inform them I was waiting. I told him about calling in about the reservation and the hotel said it was 3pm check in time. He said "no, its 4pm." (what hotel in the world has a 4pm check in? None. I travel 250 days a year.) When I told him that I had called he actually started to argue with me to the point where I became angry and said what are you going to do for us? At that point he said your room will be ready at 4 and I will call you.
We went back to sitting in the lounge and waiting...at 4 I went downstairs and he was no longer there. The other staff looked up my reservation and didn't know anything about what had transpired and had a room for me, not on the 9th floor as he had promised, but on the 4th floor. When I asked what had happened to all of the rooms on the 9th floor they said that had all been taken.
I will never stay here again, the server in the restaurant had the same attitude, and when we ordered a carafe of wine he brought two glasses, no carafe, and then charged me for it. if you want to have a boutique hotel stop hiring hipsters who have no interest in service. bad.
