I would rate this 4.5/Very Good if it were an option. Is it the Fairmont? No. but a great choice for a budget friendly getaway. Hotel was clean, updated, fun vibe, easy walking distance to Wharf, cable car, Lombard St. Ghiradelli Square, restaurants and the trolly. Staff was very friendly. Felt very safe and secure (travelling with my teen daughter) with key card required for elevator.
Not in any hurry to return to San Francisco - but would defintiely recommend the Marriot Vacation Club!
