Vacation with dughter

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.

Average

If it wasn't for a business trip, I wouldn't have continued to stay here. First day there, and there was hair in the shower and sheets were stained and torn. The room definitely wasn't properly cleaned. I was offered a few credits for my troubles, which looking back was the bare minimum. But turns out the employee forgot to add the credits, when I later checked, but I at least got a breakfast voucher to make up for it. Note - When I called, housekeeping did come up to properly clean and I got new sheets so I'll give them that. I was in Tower 3. My colleagues were in Tower 1 and had a better experience so it may depend on which tower and room you're in. The walls in Tower 3 were pretty thin. Could hear my neighbors. For a hotel such as Hilton, I was expecting better. Hopefully they upgrade the rooms. This may not be much for some people, but when I travel I want to feel comfortable and here I did not after that first day ruined it. I should've been offered another room.

Nice hotel

clairer622 (Yarm, United Kingdom) on Oct 31, 2025

Lovely hotel with pleasant staff Resort fees were given back in credits which we used towards breakfast , which was great Room was clean, comfortable bed , coffee supplied (was very nice coffee) The autumn display in reception was so nice The only thing that let it down was location for us ....we mainly wanted to be down fishermans wharf end, so was $20 every trip we did....rode in a Waymo which was cool ?? We did walk it a few times, but felt a bit sketchy at night

Great Location!

IClean4Fun (Cary, IL) on Oct 24, 2025

Great location in Union Square. We were able to check in about 1030am which was greatly appreciated. Sky lounge/bar on 46th floor has been amazing views of the city. We stayed on the 16th floor in tower 3 right off the roof top pool. Our room had Crabtree shampoo, shower gel, conditioner and lotion along with a coffee maker. King size bed was comfortable. Housekeeping will make up room and replace towels put on the floor. Overall a good neighborhood, stray homeless people down the street kept to themselves. We would stay here again.
