Great Value
We found the Castle Inn on the Hotels.com site and then checked the reviews from Trip Advisor. We found everything to be as described. This is not a five star hotel; it is an Inn. As such, the managers, Marshall and Arlene, do a great job of keeping the rooms clean for guests. We were quite comfortable in our 3rd floor room. The hotel is only 1/2 block from bustling Polk Street where we could find places to eat, drink, and shop. We even found a hardware store 2 blocks from the hotel. Using our muni-pass, we explored much of SF by walking no more than two blocks to a cable car or a city bus. If you drive to the Castle Inn, the parking is free, which is not possible in most city hotels. The complimentary breakfast is nothing fancy; you take a tray back to your room to eat. Granola bars, oatmeal, yogurt, coffee, and tea are available every day. The best thing I can say about the Castle Inn is the way we were treated. Marshall and Arlene always wanted to know if we had a good night and they were knowledgeable about city events and locations. This is an extremely good value considering the location.
