If you're looking for somewhere in the heart of downtown SF on a tight budget this is definitely a good option. It's right in the middle of Union Square, decently safe, and employs friendly staff. But be aware that the walls are pretty thin - we heard a lot of thumping and people running around the halls each night. Between that and the room being uncontrollably warm, it was hard to get a good nights sleep...and when you're in the city for a conference, sleep is pretty necessary. Also know that the airport shuttle is $12 per person and not for your entire party...we were in for a nasty surprise after being told otherwise by the hotel staff.
