Checked in, got room key and went straight to my room. Key worked, and I went into room. Room was already occupied and I was mortified. I Went back down to the Check-in and told the gentleman that was working.He said what and then he just exchanged my keys.For another room, no apologies given. My room was filthy and The shower door didn't work and wouldn't stay closed. We spilled something on the comforter and called for housekeeping and ask for new sheets.The gentleman brought them up, dropped them off at the door when we asked if we could have another comforter he told us no there weren't anymore and then he left. We had to make our bed ourselves and slept 42 nights with no blanket and or comforter. The fire alarm went off 3 times the first night and the customers were all standing in the corridor wondering if it was safe?We received no input from the folks working at the hotel at all , so we eventually stood out there long enough and decided to go back to the room , hoping it was ok. Once we arrived, we found that the pool was closed as well.As the hotel's restaurant was closed and they offered to shuttle us around the city to eat. When I reached out to the hotel manager to make him aware.He sent me a three line email asking who the housekeeper was and ignored the rest of our issues. I called Hilton today and was told after a 30 minute.Phone call that an incident report had been reported by the hotel and they were going to refund me one night . I would avoid this Hilton hotel at any cost.The customer service is Horrific and the hotel is run down and delapdated.I would like to give you a positive from the trip.I just don't have any and I am very unimpressed with Hilton's service recovery.At this point I will never do this again
