Friendly/helpful staff, bottled water daily, refilled soaps/lotions, clean room, breakfast made-to-order (omelettes and eggs/hashbrowns).
Drawbacks: my trash wasn't taken out one day, so I had to call to have it taken out that night. And I was on the top floor, which was half smoking - my room smelled slightly like smoke one out of my four nights there (also, I didn't even know there was such a thing as a smoking hotel room still? maybe i've just lived in California too long) ;)
