Great little boutique in the heart of the big city...

Location is great, right off union square and small intimate property....nice happy hour and expanded continental breakfast, plenty to get you going in the morning. Super comfy beds and pillows. Prefer this type of hotel over the big brands and the staff is very helpful and friendly...Ms. Anna has a ton of energy and personality...nice change of pace from the robots at other hotels that don't look up and say "checking in?" ... great little property worth checking out in the heart of the city.

Wonderful Boutique Hotel

My fiancee and I were visiting San Francisco for a long weekend and booked at The Inn at Union Square due mostly to it being one of the cheaper options in the city. We were blown away by the friendliness of the staff, the room size/cleanness, the area, and the complimentary amenities.

The hotel offers a free breakfast every morning from 6-10 AM along with free Peets coffee. They also had complimentary wine available every night from 6-8 PM and delicious fresh baked chocolate chip cookies from 8-10 PM every night as well.

Our room was very clean and the beds were extremely comfortable. If we had any questions or requests, they were answered and attended to immediately.

We will most definitely stay at The Inn at Union Square on our next visit to San Fran!

Always a great experience!

I have been staying at the Inn at Union Square for over 20 years when I travel to SF on business. I am a Marriott Platinum Elite member but opt to stay at the Inn whenever I can. The staff goes out of their way to make you feel "at home" and that is the difference between staying at a hotel and at the Inn. It's quiet, peaceful, and the amenities are great. I love when I come back after a long day of work and can enjoy a quiet night in my room with the nice robe they offer and 24 hour coffee, tea, water, etc. Especially the wine and cookies at happy hour! The best part is waking up early (I'm usually on EST time) and being able to go to the second floor and grab a cup of coffee until they serve breakfast. The rooms, beds, and linens are upscale, but the price is reasonable for business travelers. The Manager and the staff couldn't be nicer.

Friendliest hospitality and a great base in San Francisco!

We had a quick stay in San Fransisco, arriving after a long flight from Italy. We were immediately welcomed so warmly by the reception staff and given a swift check in so we could get right to our room to relax. We were upgraded to a corner room that was incredibly spacious. The bathroom was beautiful and well appointed and the king size bed so comfortable!

It was really a treat to come down to breakfast each morning included in our rate as well as the wine happy hour and evening fresh cookies! All of these special touches made this feel like an inn in a small town, right in the middle of bustling San Francisco!

The location was right on Union Square which made it incredibly easy to get around the city and it was a quick Uber to some of the best restaurants in the area.

Thank you so much to everyone at the Inn at Union Square! We wouldn't hesitate to stay again on our next trip to San Francisco!

Just OK

Reading some of these other reviews, I can't help but wonder if they are all real. This hotel is...okay. No major complaints, but it just isn't as nice as it comes across in this profile. The room was extremely small - there was no way to fit an open suitcase in the same room as our bed, which was down a narrow hallway from a sitting room. The bedroom window overlooked an alley. Lots of noise from the street. The decor is dated a bit from the time of the photos that appear on this site. The bathrooms/shower seemed a little dated and dingy. When we arrived an hour before check in to see if our room was ready early, the man at the front desk (literally, a desk in a tiny vestibule) was pretty rude to me. There is complimentary wine and cheese in the evening, but it's in a very small room which we mostly found awkward. Again - not a BAD hotel, just not a GREAT one either. I was expecting nicer.
