Internet not free
Aesthetically a beautiful hotel. Luxurious , vibrant lobby and attention to detail was amazing. the location was amazing, in the heart of union Square .
The location, staff were helpful
This is not very family oriented hotel, more suitable for business people and adult travelers
Location was good, right in the centre off Union Square. The service was Ok and the rooms were clean.
Hotel was quite old, in need of modernisation. The room facilities were poor and dated and the breakfast was pretty limited. For what we paid, we expected and could have got better, I wouldn't choose this hotel again.
Included in the room was breakfast in the top floor club room
Breakfast was very limited and no hot foods only continental.
The discounts on booking.com (34%), the friendliness of the staff. The staff at the lobby were also very helpful.
It would be better to provide free wifi within the hotel rooms.
Very friendly front office staff. When we had issues in the room, this was solved very well and with extreme personal attention of the front office person
The roof top terras was closed and also rather small.
I liked its location to most seen sites in San Fran. Staff was great from the doormen to the management. Great food
Chipping wood furniture. 2 light bulbs were out. Make up on wall of bathroom from previous stay. Very expensive parking on site...but very convenient. Semi-expensive room rate
Location. Safety, Satff
Quite pricey - but then all the hotels in this area are.
Location , staff , food
Very good location in SF with good restaurant/bar and good fitness room. Friendly and helpful staff. Great bathroom.
Very expensive valet parking fee and it is not OK that wifi is not for free except in reception area. Rooms seem aged but are still OK.
Location was great....within blocks of Union Square.
Walls in hotel rooms were very thin. Could hear the conversation coming from next room.
Very expensive. .Not friendly .
Great location in city centre, all staff polite, attentive and helpful Modern up market feel to hotel
Internet free for basic would be useful Would be a nice touch to provide some crisps/nuts/pretzels with drinks in the bar area
very small room for 3 adults versus the money we paid
At first I was put in a room with the smell of cigarette smoke, however I was moved as I requested.
Location is perfeck
Old hotel , car parking is too high.
Because of the location ! and the comfort
Very friendly and helpful staff, great room, etc.
Location Amenities Staff friendliness Proximity to local interesTS
The view was amazing. The bed and sheets extremely comfortable. Windows that opened kept the room well ventilated.
Two years (?) worth of dust on the floor in front of the desk. Room tax made room a lot more money than I was expecting.
