Great experience thanks to Antonio
Pros:

We had a very pleasant stay in very central San Francisco. The room was well equipped and cleaned. When we came we were greeted by Antonio, who helped us check in. He kindly offered us a room on higher floor, which would be less noisy in the morning so we could sleep in.

A very nice, small hotel
Pros:

A very nice little hotel with personal touches throughout. Housekeeping comes everyday to refresh the room without needing prompting which is becoming a rare thing in 4* hotels. The continental breakfast was modest but satisfying with pastries, bagels, fruits and yogurt available. All in all, highly recommended

Birthday Stay in the City
Pros:

We’ve stayed numerous times and have always appreciated the service of the staff, especially Antonio at the front desk. The rooms have always been spacious and comfortable. The rooms are laid out well, wifi and tv reception are satisfactory, bathrooms have adequate water flow and pressure, very clean rooms, and comfortable beds. The maid service is exceptional. The breakfast room is well stocked. The parking is convenient and reasonably priced.

A great spot for a nice getaway to the city!
Pros:

Perfect spot at a reasonable price! It's an older building, but the noise level is very good, could barely hear anything neighboring. The decor is really lovely and fitting for the time. Esly front desk was super accommodating and the sweetest! The rooms were clean upon entering. Very comfortable bedding and a cozy room. Amenities were simple and efficient.

Warm Welcome
Pros:

A Wonderful First Impression of San Francisco

I just arrived in San Francisco, and staying at Inn at Union Square has already made my trip feel special. From the moment I walked in, I was welcomed with genuine kindness and warmth.

A special thank you to Antonio, who was incredibly friendly, professional, and helpful. He took the time to answer my questions, made me feel welcome, and gave me a great first impression of both the hotel and the city. His outstanding customer service truly stood out.

The hotel is charming, comfortable, and perfectly located for exploring San Francisco. I’m excited to continue my stay, and based on my experience so far, I would definitely recommend Inn at Union Square to anyone looking for a place where the staff genuinely cares about their guests.

Goo location with $25 extra fees for nothing value
Pros:

If you booked trough Expedia you will pay twice.
The location is good, the room is good and clean.
Hotel ask for $25 day fee for some pastries and bagels they called breakfast (offered on Expedia as part of the price), purified HOT water and ice.
Nobody wants to listen to your concerns or complains.
