Great location!
The building is old, which we found charming. The service was good, helpful and professional. Perfect location if Union Square is what you want, great restaurants and shopping close by and very “walkable”. We prefer to stay in this area over any other in the city.

Overpriced, too small, bad smell in the room, dirty carpet, tiny elevator and hallways and the valet is NOT included. Galleria Park Hotel had the same price, a great lobby, spacious clean rooms, and valet parking. I will not stay at Inn at Union Square again. Thank you!

Old, stodgy, and smelly hotel
After looking at over 50 hotels, I ended up staying at the Inn at Union Square based on the reviews. Upon walking into the hotel, we were met with a powerful stale odor that smelled like old cigarettes. This was supposed to be a non-smoking hotel; however, it seemed like they took over a building where smoking was permitted and done so heavily. Because we have insomnia, I specifically asked to be placed in a room that was away from the elevators, stairways, lobby, and street. Somehow, some way, we were placed in room that was adjacent to ALL FOUR. It was shocking. Not only that, at around 12:30 am, street construction commenced where construction workers began placing concrete. To top it all off, once we checked out and gave our valet ticket to the front desk, we waited for *40 minutes* for our car to arrive. It was in the low 50s with wind, so it was very cold, but the stench from within the hotel was so strong that we preferred to stand in the cold weather. Mind you, after asking the front desk for status twice, we found out the garage was around the corner! We could have walked to it 40 minutes prior. I don’t know if this was an inexplicable mistake or done intentionally, but from the beginning to the end, this hotel fell FAR below expectations. This is not the first time I’ve been deceived by reviews, but having paid over $300 for this one-night stay where $55 of it was for a for a valet service that wasted our time, I would never, ever stay at this hotel again.

The location is superb! Really close to Union Square (less than a minute's walk) but much quieter. The bed was the comfiest hotel bed I think I've ever slept in! Room 501 is our recommendation- worth the extra over a standard room. It was so quiet and spacious, for a San Francisco hotel. I've read reviews where people complained about the breakfast, but seriously it was fine. Choice of pastries, fruit, coffee, tea and juice- enough to start you off for the day. If people dont like it they have the choice to go out and buy it, but we thought it was perfectly sufficient. The staff were all very friendly and helpful, every one. We would DEFINITELY recommend this hotel to anyone.

Superior king bed is pretty uncomfortable, super fluffy, pillow is old and doesn’t offer support to your neck. There is no AC, only heater. The bathroom is good and the decoration is beautiful. Breakfast is standard, with no hot servings (like scrambled eggs)
