Location is great for my work trips as my office is downtown, and it's an easy walk from BART, to the office, and/or ride from the airport.
It's on the edge of the Tenderloin, so the street life and activity can feel a little edgy at times, but I've never felt unsafe.
Love the lobby decor and the rooms are modern but warm and comfortable. Beds are comfy, black out blinds. Sometimes you hear some street sounds, but I travel with ear plugs, so it's never been too much of an issue.
The staff are super friendly, the coffee is strong and solid and flowing at 6am - 10am, and really appreciate the gym (basement, but clean and the equipment works). The adjoining restaurant is also convenient and reasonably priced - especially during HH.
