I had a great stay at The Inn at Union Square The front desk staff were incredibly friendly, welcoming, and always willing to help with anything we needed. The place was very clean quiet and comfortable, which made my stay even more enjoyable. One of the best things about this hotel is its excellent location it's just a short walking distance from the luxury brand stores and other attractions in Union Square. I would definitely stay here again and highly recommend it to anyone visiting San Francisco

Staff was friendly. Check in was seamless, and we were allowed to check in early. That was amazing and super helpful. The property has very comfortable beds and pillows. The breakfast is very basic but satisfying enough. The property is convenient to a trolley stop and you can cruise around anywhere you want with minimal walking.

The hotel was nice overall. Antonio was very helpful at check-in and very kind to offer an upgraded room for our stay. The room was comfortable and clean. Check-in was a bit chaotic given you have to unload/park on a busy street, but being near the busy street was a plus, given you are near public transit. The location is super nice for that. Breakfast offerings were standard, but you should try local spots for food!
