Great stay at Inn at Union Square
Pros:

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.

DONT book here!!!’
Pros:

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
Pros:

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.

One of the best hotels in SF
Pros:

Since booking, I already have great expectations from public reviews. However, the experience couldn’t have gone any better after actually staying at the hotel. The location is really nice, you can go to union square just by a 2 mins walk, you can find food, walgreens, etc. nearby with ease, even public transport access. Then, I was greeted very warmly by EACH AND EVERY ONE of the receptions. On my final night, my room was even upgraded and I couldn’t thank this hotel enough that my stay here is really enjoyable and unforgettable.

Graduation celebration trip
Pros:

Cute boutique hotel for mother daughter celebration trip. The room was super clean and cozy. Decor was up to date. Staff was warm and friendly. Simple continental breakfast and good coffee. Convenient and safe location for us to walk the city. We planned ahead and knew the areas to avoid. Hotel is set between two fantastic restaurants as well.

Would stay here again!
Pros:

Great quality rooms and a very good location! The hotel felt safe and was next to Union Square, Powell street, and walking distance (10 mins) to Moscone center.

Cons:

Didn't love that we had no AC in the rooms. We had a ceiling fan and left the windows open, which made the room cooler, but no AC. Would've liked to know about this beforehand, maybe I didn't check well enough :)

Pros:

It was safe, quiet and central. I was sick during my stay, and I spent a lot of time sleeping. The bedding was very comfortable! I also appreciated that it was walking distance to lots of restaurants and transportation. It was also nice that the hotel offers a continental breakfast.

Cons:

The hotel is in an old building so it appears a bit run down at first. But once I adjusted my expectation, it was totally fine. I can appreciate the charm of it. (I only mention this in case anyone is expecting something modern). As I mentioned before, it was well-kept, clean and comfortable. And very central to what I needed from my stay. I would stay here again.

Hidden gem
Pros:

This hotel is a hidden gem. Literally hidden as I walked past it twice before figuring out what google map was saying. The entrance is tiny, with a tiny reception but the service was warm and friendly. My room is on the 5th floor, serviced by a small older elevator. My room however was nicely updated and very clean! Wha a nice surprise. And the ceiling fan was perfect to keep the air moving and at a perfect temperature.

A continental breakfast is included, which is appreciated. Selection isn’t huge but perfectly adequate. And the location is perfectly walkable to streetcar, hop on hop off, major shopping and Trader Joes. Lots of cafes and options around. Price is more than fair for a San Francisco boutique hotel. Would definitely recommend!

Hidden fees and cleanliness issues
Pros:

The room itself was decent, but the experience overall was unacceptable.

When I went to use the bathroom, I found brownish-yellow water in the toilet, like it hadn’t been flushed after the previous guest. It’s hard to understand how housekeeping could miss something that obvious, and it immediately made me question the cleanliness of everything else.

What made things worse was the deposit situation. I prepaid for the room in full, and your own email clearly states that the $200 security deposit is only charged "IF YOU DID NOT PREPAY YOUR RESERVATION IN ADVANCE", which I did. Despite this, I was still forced to pay the deposit at check-in. I even showed the written policy, but the front desk staff dismissed it and told me I was wrong - even though I showed the statement IN WRITING to her. From then on, she was rude, dismissive, and uncooperative.

Because of this, I had to use my debit card unexpectedly, and I’m still waiting on the refund - minus a $25/day “amenities” fee that doesn’t seem to correspond to any actual amenities other than a free newspaper (that I didn't get) and a fax machine that was available for use. Since we aren't living in the year 1995, I used email from my laptop in leu of the thoughtful and generous availability of a fax machine. These extra charges feel misleading and deceptive.

All in, I spent nearly double the advertised cost for one night, dealt with poor service, was charged contrary to the hotel’s own written policy, and walked into a bathroom that hadn’t even been properly cleaned. No chance I would stay here again.
