Vacation with dughter

Manuel D on Dec 01, 2025

Excellent service from the moment you enter the hotel, the person by door, front desk,housekeeping, you should be proud, definitely a unique group of people, thank you very much. very helpful. I went to a Francisco for a concert from San Diego with my daughter and the housekeeper on floor 37 was very nice to us. I will definitely go back and recommend this hotel. Thank you

Very mixed experience

jamesgr599 (Cheltenham, United Kingdom) on Nov 24, 2025

Very mixed feelings on this property - The room itself was nice, but the hotel has an odd feel to it. Of course it’s well documented how bad union square has gotten , but inside the hotel it’s almost like experiencing 3 different properties depending on where you are in the building. For a property this size, there’s no “proper” restaurant, which is a real miss. The gym is tiny and cramped, and I think the WiFi is probably the worst I’ve experienced anywhere; the fact that there is a dedicated WiFi support button on the phone tells me I may not be alone in that. This is where it makes no sense - no real restaurant , yet millions of dollars have clearly been spent to put a really nice sky bar at the top of the hotel, although it feels like they forgot to include the bathrooms as you go up some weird staircase to a sort of 1990s bathroom. Odd. Overall, a strange place. Decent rooms, but everything else feels like it needs attention - you can have a cocktail in a nice rooftop bar or a swim on the roof, but if you want a meal or some working WiFi then that appears to be a challenge.
