We stayed four nights of a two week California vacation. This hotel was a good base for us.
We had a room with a real wood burning fireplace. The housekeeping staff would supply a burlap tied bundle of wood each day for us to easily light a fire anytime we wanted.
The hotel management hosted an evening wine and cheese hour. We were able to meet the nicest people from all over the world while we stayed there!
Front desk staff very friendly each time we entered and exited the building, offering any help we needed with places to visit, to dine, or directions if needed. They felt like family after the first day.
The Inn at Union Square is in a perfect location of San Francisco also!
