Everything but most of all the city view from our room it was breath taking x
There was not one thing I didn't like
the generous size of the room and bath area, friendly staff, cleanliness, lobby was a great gathering place
no WiFi in the room, noisy air conditioner, disappointed that for the price of the room, no complimentary breakfast was included
- comfortable beds - pool and jacuzzi areas were nice
- dated interior/ decor - over priced - a number of lights/ plugs/ fittings (hair dryer) did not work
You are only a short distance from Union Square you are not actually on it. Great location to market street where the cable cars and trains etc are. Liked the hotel but food was very expensive we ate once in the restaurant.
Be careful around this area alot of homeless and area behind the hotel is not meant to be a safe area, according to the tour bus guide.
I liked that it was centrally located. Brandon at the concierge desk was wonderful.
On arrival, the check in person argued withe that I did not have a reservation. Somehow, they connected part of my first name with my last name. It was terrible to start that way. Overpriced for fair quality. I expected more from the Hilton.
Only good thing was that it was close to the Bart station.
No free wifi..seriously? Unupdated facility. Just one block away from the bad neighborhood. There must be a better choice.
Great location within walking distance to transport and all facilities
No fridge or iron for travellers
Location Facilities Fantastic Breakfast
WiFi available to any non paying person wandering into the Lobby but not to paying guests in their rooms unless they join the Hilton Honours scheme.
Good location, friendly staff and great buffet breakfast. Close to bars and clubs
Dilapidated rooms, need upgrading
Clean, and comfortable. beautiful view from tower room even comes with free Starbucks for each morning.
Wish the bed was a little more comfortable. The staff when we checked in at night had great service the morning staff wasn't so nice when we came for the first week.
Location was great with lots of places to eat nearby. Breakfast great when we got correct vouchers. Rooms very clean
We were given Starbucks vouchers rather than urban restaurant. Staff quickly changed when we pointed out but no apology.
San Francisco is a wonderful city and hotel location is excellent (near Union Square). Hotel faciilities are good. There is a starbucks on the hall.
Unfortunately, hotel staff were not as motivated as we were. If you check in at 10 pm and you are tired, don't expect smiles and welcomes from them.
The location was excellent
The car parking fee was outrageously expensive, and the shower in the room wasn't very good.
Very Old interior
Clean room, lucky to have a quiet room.
The beggars that dogged you as soon as you stepped outside. The hotel did not move them on. On the edge of dodgy area. Had to pay for internet
Location and the concierge was very helpful.
You have to pay for wifi in the rooms. Disappointing.
The easy connections to Ghirardelli Square, cable cars and Fisherman's Wharf
Hidden costs that we were not aware of until we got to the hotel.
In the middle of town and a short walk to Union Square. Bed was great and room had a view :-)
The hotel is huge with many many guests... Lines can be long.. Hotel is Getting a bit long in the tooth, carpets need cleaning and rooms need a facelift. There are better value for money hotels in SF.
Right in the heart of Union square, shopping, tour buses and restaurants all within a few blocks. Really handy facility in hotel for printing airline tickets.
Sheets in hotel room had a blood stain.
The cost was 1/2 price when we booked The rooms huge and the room always tidy hand location to every thing to
Leaving to come home
Standard Hilton Hotel rooms. Clean and decently appointed but overwhelmed by the number of people in the shared areas. The restaurant was surprisingly good and not too crowded to get a table.
The hotel is so large and has so many people staying there that the lobby reminded me of Grand Central Station at rush hour. The line to get coffee from Starbucks in the lobby was ridiculous.
Rooms and breakfast was excellent.
Didn't have a room available when we checked in. So had to move from a small room with 3 beds thrown in to our original booked room 24 hours later, meaning we couldn't unpack.
- location is great
- price/quality is quite poor
