Great hotel
Loved this place. Actually I was bumped to the Mark Twain from another hotel that had overbooked my first night. Staff was super accommodating, I loved my room, location was central to shopping, restaurants, transit. One thing was I couldn't figure out how to put the heat on but it really wasn't very cold anyway, and I arrived so late, I didn't bother looking into it. I would definitely consider the Mark Twain when returning to San Francisco.
