The room was very small. That's OK, but it did not have a chair and the bench they provided was very uncomfortable. There were no toilet rolls and I had to ask for them; first time it happened to me.

Great location. Walkable to the Gaslamp district. Quick Uber to everywhere else. Bed was super comfy. Didn't like that I wasn't offered my free room upgrade. Lower tier rooms isn't anything to brag about.
