Hotel was clean, room was clean. We were on the 4th floor and the room wasn't sound proof at all. We were periodically woken up by children in the room next door, people walking the halls, etc. Furthermore, housekeeping started knocking on doors at like 9am when checkout isn't until 11. Which would be fine if the rooms were more sound proof, but in this case we got pretty poor sleep. Not a great hotel experience.
