The room was clean, comfy, cozy, and updated. Hotel staff was very friendly and welcoming. There’s no hotel specific parking but there are nearby parking garages. It’s literally right next to Union Square. My only tiny complaint is the lack of outlets. I’d stay again!

We enjoyed our 4 night stay here. Room was very clean and quite. Love that we were able to open the window! All the staff were very lovely. They have a great filtered water machine in the hallway. My only complaint would be the hallways and lobby have maybe a lil too much fragrance/air freshener, but luckily the rooms are not this way at all. I would definitely stay again.

Really comfortable rooms. Very convenient location with numerous different shops, bars diners, etc within 2 blocks. Hotel doesn't have its own bar or restaurant and the Continental breakfast is very limited for the price that is added to cover breakfast. And it doesn't open until 8am on weekdays... As we had to be at our event prior to 8 it was useless to us. Our team liked their rooms, and other amenities. I would have no issue staying there again.

Overall a good location close to Union Square. However one cannot go to California these days without feeling ripped off. The $25/day ‘amenity’ fee is levied whether you take breakfast or not. It’s just yet another form of taxes due to exorbitant costs associated with running a business in CA. The hotel is quiet and overall clean with comfy beds. Be prepared for a lot of homeless and people wandering around with mental health issues. SF is a great city but has its problems.
