Despite how busy it was in San Francisco at the time of our visit, and the hotel being at full occupancy, the lobby was surprisingly calm & quiet and the staff friendly & helpful. Huge, elegant guest rooms offered good views in any direction (on higher floors). Well located very close to Union Square and Market St, and a cable... More

Right in the centre of the city is where you want to be. The hotel is five star and the staff,restaurants and rooms are all accordingly of that standard. Typical good Marriot hotel.No trouble finding us a quieter room on a high floor and they saw to all our petty requests.

Have stayed multiple times in San Francisco and truly enjoyed the Mariott. I had booked with Mariot points and had a reservation for a no-view room but ended up at the 26th floor with a breathtaking Bay view room, small but very new, clean and comfortable. Location is fantastic - 1 block to Union Square - great shopping and restaurants... More

I was pleasantly surprised as to the location of the hotel as it was convenient to BART rail system which we took directly from the airport for $8 each! The hotel conceirge mentioned it to me prior to arriving on the phone when I asked about shuttle service. In addition, the surrounding area provided shopping and nice restaurants. The corner... More

The room was nicely decorated and clean. We were on the 25th floor and the view was awesome. The hotel staff was friendly and helpful. My only complaint is the cost of parking.

this place has had a remarkable changeover. the rooms have all been updated with especially nice bathrooms. if you're from europe and/or are used to "european standards" for hotel rooms, you'll be quite pleased with this hotel. and, epecially for out-of-towners, you will not find a better, more central location--Union Square, Chinatown, Yerba Buena are just a few steps away.
