I really liked this place. It was perfectly located within walking distance to Moscone Center and the RSA Conference shuttles drop off and pick up within a half a block.
As I mentioned in the location part, know that the accessible entrance is at the attached garage entrance on Mason if you are using ground transportation. Don’t make my mistake of being dropped off on Post.
The hotel has reasonably priced on-site laundry service but no facilities to do your own so pack appropriately. I wish I had taken advantage of the laundry service rather than pack so heavily.
