Room was clean and staff were friendly and helpful. The room was cleaned daily and coffee available both in the room and on floor 2 during morning hours. Air con worked but was a touch weak as I like a cool room.

This is a nice boutique hotel located just off Union Square (and across the street from the St. Francis). The front desk staff were delightful and the cleaning staff were thorough and timely. There are a few signs of wear & tear around the property, and at one point the (only) elevator was out of service for several hours, but I think this is to be expected in an older SF hotel. I would gladly stay here again.

This tiny hotel was exactly what my team needed for our work trip-- the daily free breakfast was substantial enough and the rooms were spotless and comfortable. I had a suite which was perfect for my 4 night stay.

My wife and I were extremely satisfied with our clean and neat room. The staff was very helpful and checked us in quickly. Antonio and Liel were perfect hosts and made sure we had the “right room” for our stay. They’re a very good and efficient service team. Also great location close to every thing, especially the cable cars; shopping and the wonderful Union Square. Macys and Ross are right there.

This hotel has character! The historical property with recently renovated rooms is very comfortable and feels like it has a soul, as opposed to a big chain hotel. Very clean throughout, and the rooms are gorgeous. Antonio at the front desk started our stay off with smiles by upgrading one of our rooms. The staff was helpful with deliveries we had on the first day, which was a huge relief. The hotel is just a half block off Union Square and is surrounded by restaurants and bars in each direction. This property has neither, but we didn't miss it since they were steps away. There's a parking garage in the same block for about $40/night. Elevator and hallways are narrow - to keep in mind for accessibility - but otherwise a very comfortable spot we wouldn't hesitate to book again!

My boyfriend and I had an amazing stay in the speckles suite! The huge room was nice for spreading out our things to get ready in the morning, I loved the access to the continental breakfast for a quick snack in the morning and endless coffee! The bathroom is huge, we had plenty of space to get ready for the day quickly. Great location and staff, the room was exceptionally clean. Will definitely be back!
