Top Union Square Hotel Reviews

Hotel Spero, Vignette Collection by IHG

10/10 Excellent

"Nice and clean, newly renovated. "

Chancellor Hotel on Union Square

10/10 Excellent

"I enjoyed my recent stay at the Chancellor Hotel on Union Square. The hotel was a reasonable price and had everything I could wish for - especially wonderful staff and a clean and secure environment. I felt very well looked after from the moment that I checked in. The parking was convenient and the rate was competitive for the area. I love the location and the historic San Francisco flavor of both the neighborhood and the property itself. The hotel does not offer air conditioning, but the room I had was well-ventilated and equipped with a quiet, but efficient, ceiling fan. San Francisco is famously cool at night most of the year anyway. I look forward to staying at the Chancellor again and recommend it highly."

Taj Campton Place

10/10 Excellent

"The staff were all unbelievably kind, on another level. I worked at Disney and know a think or two about good guest service, but these folks felt genuine. Dan at the door helped us with everything we needed. We didn’t look like the other clientele. We were scrappy little punk emos taking up space in a refined lobby and they still treated us with the upmost kindness and respect. We wanted an early check in and it wasn’t available. As soon as they could they got us in 30 minutes before check in and upgraded our view for our patience. I will be staying here again no questions asked."
