Room was clean bed was comfortable the shower did not work. I had an early flight (I was up at 4am) and could not turn the shower on, the handle kept spinning. I needed to use the sink to take a shower.
When I went to check out I was told that the computer was down and they were going to discount my room, as they should. I just got the bill, no discount. I tried to call and you can only guess I could not get through. Two reasons I stay at a hotel. A comfortable bed and a working bathroom.
