Amazing staff and a comforting place to escape the hustle and bustle of SF

I have lived in San Francisco for 15 years. We moved away because of the hectic pace and wanted a simple life. We had to fly back for a few days and work randomly put up in the Inn Union Square. I can not rave more about the staff at this hotel! They are incredible!! They are beyond accommodating and always make you smile. After wandering around the city it’s nice to come back to a place where people call you by name!! They put us in room 605 and it was a very spacious suite with a beautiful bathroom,and super comfy bed. The breakfast was nicely done ( even the woman maintaining the breakfast station was greeting everyone like they were long lost friends) Overall I cant say enough about this hotel and I highly recommend it!

This is our new favorite place to stay in San Francisco!

The hotel is well located, quiet, extremely comfortable beds and charming atmosphere but the best part of the hotel is the attentive and friendly staff. From the minute you walk in and are greeted with a glass of champagne you know your stay is going to be special.

Disappointing. Has lost its charm

Having stayed at the Inn on many occasions thirty years ago it was with eager anticipation that we looked forward to returning. Unfortunately it has had a makeover and it now is indistinguishable from any other higher end, neutrally decorated, hotel. The first "suite" we were offered was small and dark. The second suite was marginally better.
The hotel is clean, the beds are really comfortable, (were those reject bath towels we had?), and the staff are super friendly. Location is great but this hotel is now just one other hotel that has lost its competitive edge.

Pleasant nice people, great service easy valet for the car. Very clean, modern renovation. Small property, intimate. Nice breakfast service and wine and cheese in the afternoon is very well done. Walk to vest shopping!
