I didn't eat . Great location. A quiet, small , and quaint hotel.

There was no coffee at 9 am and no one around to make coffee, so I left and went elsewhere.

Camera piccola ma con tutto l’essenziale. Letto comodo. Colazione buona

A colazione c’era un solo tavolo con 10 sedie e non ci si poteva mettere su un tavolo da soli. La doccia un po piccola

Great stay at Inn at Union Square

We had a great stay at The Inn at Union Square. The cost was very reasonable compared to other hotels in the area. We were able to check in a little early, they allowed an extra hour on check out, and stored our bags for a couple hours. Our king studio room was a good size. We did not realize we wouldn’t have air conditioning (we may have just overlooked it), but the room had a ceiling fan and the ability to open the windows cooled the room nicely. The location is perfect to explore SF. Esly was an employee we interacted with a few times and she was exceptional. Look forward to our next stay here.

This hotel charged an additional $50 to my credit card without my authorization and continues to make unauthorized charges. I will be reporting this matter to the appropriate authorities and consumer protection channels. I will also share my experience publicly so that other travelers are aware of this situation. Based on my experience, I would not recommend this hotel to anyone who wants a positive stay. Be very careful when providing your credit card information and make sure you fully understand all charges before checking in. In my opinion, this was one of the worst experiences I have ever had with a hotel, and I am extremely disappointed with how this situation has been handled.

Would Stay Here Again in a Heartbeat

+

My mother, sister, and I stayed at Inn at Union Square during our visit to San Francisco, and it turned out to be a wonderful find. The location is excellent—less than half a block from Union Square. Two tours we booked picked us up right near the hotel, including one directly across the street, which was incredibly convenient. Our room was spacious and included a lovely separate seating area that gave us plenty of room to relax after a day of exploring. The complimentary continental breakfast was modest but exactly what we needed to start the day without feeling overly full before heading out. There were a few minor issues. Some of the wallpaper in our room was beginning to peel in places, and the bedroom blind was broken and would not open. Most of the staff were extremely helpful and welcoming, although I had an unpleasant phone interaction with one staff member before our arrival, and another employee was only moderately helpful. Those small issues aside, we thoroughly enjoyed our stay. The location, comfort, value, and overall experience far outweighed any shortcomings. I would stay here again in a heartbeat and would happily recommend it to others visiting San Francisco.
