Beyond their control
Great little hotel, super convenient to everything, Anne at front desk is a treasure, staff was beyond helpful, room was well appointed. St. Francis hotel was being picketed, however, and the daytime noise was horrible. Not conducive to a relaxing stay, and beyond the control of the Inn.

A Charming Inn
This Inn is charming, clean, very well located with international guests, We met couples from France, England, Australia and Scotland! Wonderful coffee and morning breakfast spread and evening wine and cheese hour. The staff is wonderful and very helpful. We thoroughly enjoyed our stay. We will return.

Very Good8.0
Very pleasantly surprised! Staff was amazing ... room was spacious and more than comfortable - would have liked to have had a coffee maker for early morning but the breakfast reception room had great bites and coffee - just sometimes you don't want to get dressed to grab a cup of coffee - am I right? Great location - a quiet, charming, place!

Good choice!
Great location within walking distance of many interesting stores, restaurants, and lovely sections of SF. Very quiet. The staff were accommodating and warm. Breakfast was excellent and gave us a chance to meet a few of the other guests in the hotel. Hard to beat.
