My wife and I stayed in the hotel from December 28 - January 1. We were very pleased with almost everything about this hotel.
The check-in desk was very efficient and friendly. Our room was ready for us upon arrival at 2:00 p.m.
Location: The hotel is not in a highly touristed area, which, in some ways, worked to our advantage. We never thought we were mobbed by other tourists all trying to do the same thing. Having said that, Market Street and Mission Street were just a few blocks away.
Hotel Amenities: There is a small Starbucks in the hotel lobby. It was, unfortunately, only open until 3 p.m. which seemed too early. Perhaps it had special hours because of the holidays. There was a lobby bar that was open from 5 p.m. - 11 p.m. The food was expensive but they had a good beer selection and the staff was super friendly.
We did not try the restaurant for breakfast.
There was a small fitness center and good sized swimming pool. The pool area was a little dark, however and didn't lend itself to hanging out. The pool was warm and the hot tub was welcome after a day of sightseeing.
Room: It was a very typical "Courtyard" room. No refrigerator and the TV was in a surprisingly awkward location for watching from bed. Excellent heat/ac system. We had a king bed and the room also had a love seat. If we had a complaint about the room it was the the light switches were in confusing locations and there were too few electrical outlets for the various laptops, cellphones, battery chargers, etc. that we had with us. Marriott should be commended for the high speep internet access that they provide for free in the rooms. Very useful for checking flights, looking up museum hours and ferry times, etc.
Other items: There are a number of good restaurants nearby. We had New Year's dinner at The Fly Trap, less than a half block away and it was excellent. There is a liquor store directly across the street. There were a number of "fast food" places within easy walking distance (beside the Starbucks, the closest was a Subway and a local Mexican place). Taxis were almost always available outside and the valet also had towncars available. Gray Line picked up and dropped off in front of the hotel if you book a tour with them.
This hotel is a great location if you are doing things in the vicinity of Yerba Linda Gardens, the Moscone Center, the Metreon, and the Westfield Mall. They are all within 6 blocks or so.
This Courtyard seemed of a much higher calibre than the one near Pier 39/Fishermen's Wharf.
