    The hotel is very conveniently located near Chinatown and a less than a 20 minute ride to Fisherman's Wharf. Being a Marriott Bonvoy member I received a free room upgrade to a suite which was very nice of the staff. The room was spacious with a comfortable bed and a walk-in shower. The drinks at the Level 3 bar were good but pricey. I was not happy about the hotel's $38 destination fee. It's a completely made up fee by Marriott and is not mandated by the city. Marriott does not mention this fee on their website. They inform you about it when you check in. They charge this 'destination' fee EVERY DAY you stay there and you can't opt out of it. Even more infuriating is they give you back $20 in credits each day but you have to spend it that day or lose it. You're forced to use these stupid credits at the hotel. We ended up buying overpriced $7 bottled water and snacks every day at their tiny convenience store.

  • Engine customer Apr 2026

    Breakfast items extremely pricey. Waitress was excellent.

  • Engine customer Apr 2026

    This hotel has the perfect location but should have a Michelin star restaurant or at least a Morton’s level restaurant

  • Engine customer Apr 2026

    Great staff, shout out to Bianka for starting our stay with such a warm welcome. Clean, spacious room and lobby. Level III served excellent food - great staff there as well. Loved the location of the hotel. There are overnight parking garages right across the street for $40/night. Would stay here again.

    The service from the Employees are top notch .. My wife and I have stayed at many nice hotels and they are all nice but it's the service from the Employees that brings us back, The employee ( Norvin) goes far beyond his duties to make our stay so much nicer, he always remembers us and his hospitality is second to none, Our next stay we talked about the presidential suite and Norvin gave us the tour of that room, It's fabulous. We will keep coming back and tell all our friends where to stay in the City, and location is fabulous ... Thank them all for another great stay ... There is not much ... The only thing I experienced was the young man at Valet desk after hours ... I am an early riser and I smoke so I take trips out to smoking area When I did on this trip, I went out to smoke and the young man was asleep, and the second time I exited to smoke he was on his phone, I said good morning and he ignored me or maybe he didn't hear me ... The young lady at bell hop counter did and she responded and ran over and open the door on valet side, ... That's about all ... The day guys are fab

    The Valet parking was quick and easy. Plenty of shops, restaurants and attractions nearby. Anthony was extremely helpful when checking us in and out.

    Excellent location and very clean. Pristine rooms with a spacious bathroom.. The bed was also very comfortable however, for a hotel in this category, we felt it lacked some amenities and atmosphere .there wasn’t much happening in the hotel and many things seemed to close quite early. Our room was supposed to have a city view, but it almost faced another apartment building. We also tried the Hotel breakfast one morning and found it quite pricey. Overall comfortable stay in great location, but it didn’t fully meet expectations for this level of Hotel.
