When I check in, I live in room number 620. I found out that there is a empty water bottle in refrigerator. I kindly tell the reception desk this situation. The second day, they clean well. Then house keeper manager knock my door and ask me any question. I siad everything is fine. Because of fly cancel, so I book one more night. I went to supermarket to buy some pasta and wine. When I finsh my eating, I put the plate on the desk. The next day, when I back in the evening, I saw plate still there and glass which I drink last night no clean, just put on the desk. Then I take the used plate and glass go down to reception. The house keeping is really very very bad. If it is samll hotel, I have no words to say. But it is Hyatt. The most famous hotel in the world.
