Clean, decent room size & layout, comfortable bed. Wifi was acceptably fast (standard Marriott 15Mbps) and pretty reliable.
Shower was a bit finicky to get the right temperature, but plenty of water pressure and temperature consistency.
Very little noise from outside - just the pool really, which wasn't much of an issue on the 7th floor anyway - but the walls, ceiling, and door to the hallway were all pretty acoustically transparent. Not a huge amount of noise from them overall, but enough to be a little annoying.
