Location, price, music, and hospitality. My room was tiny but we knew what we were getting into.
The staff is extremely friendly and if the reception isn't open you can just go to the bar. It's really nice esp since there are no fridges or ice machines etc that you can just ask the bar for whatever you like.
Unobtrusive help; if you are taking a nap or etc during the day they knock very lightly and it's never a problem to go downstairs if you need a trash bag or hair dryer.
The onion rings were so freakin' good.
The music is great and a great way to end your night.
Convenient location and no frills.
