    “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.”

    “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 ...”

  • It could have been a very much better experience.
