The worst hotel and hotel service I've ever encountered! When I moved in, the guest room has NOT been cleaned AT ALL! There are left overs food on desk and bed from the previous guest! No cups for coffee machine to brew tea, obviously lacks some towels in the bathroom! I called the front desk twice, and went to front desk to talk in person later on. Hilariously, they refused to switch me to a clean room, instead, asking me to wait in the guest room for the hotel service to come to clean the room! I traveled all day long and now has to sit in my room to wait it get cleaned??
If there is zero score I can choose, I would not hesitate to give score zero. Now I can only give score 1, which is the lowest score I can give!
40 minutes later the supervisor of the house keeping came in, she was surprised to see the room hasn't been cleaned at all. She took picture of the room, and called the front desk to switch me to another room. Then, the front desk finally called and agreed to switch me into another room which suppose to be already cleaned. :-( I am doing a business travel not a personal vacation here at New Orleans, and I need to continue work tonight, just not sitting there or go out to have several cups of wines and then come back to check whether the house keeper finish clean the room or not.
1 hour later, finally, someone came and gave me the pass for a new guest room. I am wondering where is the manager of this hotel, as I asked that person is there a manager that I can talk with, he seems reluctantly answer that question directly. I told him that I already provided the lowest score I can gave in google, and I am going to do the same thing in trip advisor too. As in the check in package I saw the hotel gave me a card saying that if I " enjoy my stay" here, I am welcomed to perform review in google and trip advisor. Well, sure I am doing that ..
