I had a great pleasant stay but if you want a quiet boutique hotel this place not for you! Lobby is always super busy and lots of conventions going on at all times. I booked last minute so there were too options but was pleasantly surprised with this hotel. The view we had from our room was incredible! I could... More

This hotel is ideally located for visitors. Minutes walk from most amenities. Staff very helpful.We really enjoyed our stay and would recommend this hotel. Plenty of restaurants within 5 minutes walk and main shopping areas within 5-10 minutes walk.

Although the Hilton San Francisco Union Square is in a great location and has a great view of the city, the rooms and service were not what I would expect from Hilton for the following reasons: 1. Shower water was cold unless I used the ADA shower head. 2. Bell staff stood around behind the check-in desk instead of opening... More

The staff were pretty robotic and bored and not all that welcoming. There was no wi-fi in the old tired rooms. We were also forbidden from using the fridge as it had been locked!!

My wife is very sensitive to allergens. Our room was impeccably clean and she had no troubles whatsoever. I've stayed here before on business because it is walking distance from Moscone and the BART & Caltrain stations, so I don't have to rent a car.

The room was very nice, the hotel was close to transit including the BART line that can take you to he airport. Every hotel staff member I talked to was very courteous. Recommended and I would stay here again.

This hotel is just perfect. Nice, remodeled rooms. Awesome, friendly staff. Operation seems seemless . The lemon drop at the bar was yummy and the hot breakfast buffet is worth the price. The only negative is the parking price of almost $60 per night, but that is the going rate in SF.
