No frills but very clean and in an optimal location--perfect for the budget-conscious traveler.
There aren't a lot of luxuries in this hotel, but it has all the essentials, including a very comfortable bed. The room we stayed in was clean and in good repair.
The location is perfect. It is in one of the less sketchy parts of downtown SF, with easy access to the BART, numerous bus lines, and the famous cable cars (which stop right outside the hotel). Walking distance from Chinatown and Market St.
FYI, check-in takes place at the Stratford Hotel 1 block away from the Herbert.
