Great first time in San Francisco!
"I stayed at the Inn on Folsom for nine days for the GDC conference with a friend. It was a really great experience. It was one of the cleanest inns I've ever been to, and was kept tidy and well maintained. There was coffee 24/7 at the lobby as well as yogurt for snacks. There are no private bathrooms, but there is a sink and mirror in each of rooms. There is a toilet and three showers on each of the two floors, and so I never had to wait to use the loo. It also felt very safe because you'd need to use your room card to enter the inn. Location-wise, Folsom street is in the heart of SoMa has a bunch of yummy cafes, eateries and bars. While it's not in the midst of downtown, it's about a 5-10 minute walk to the nearest MUNI and BART station. One thing to note that it's located on top of the Cat Club bar. This makes it a bit noisy for those who are light sleepers, especially during weekends. I never minded it though. When it comes down to it, you could always request a room on the second floor (farther up from the club) Ben, the manager was great and the staff was really friendly. I'd go there again!"
