A couple of mornings the breakfast was very slow service and we had to walk out and get Starbucks because we had bookings to get to despite having left ample time for breakfast.

Great location and nice room that's about it. I expected much more from a Marriott hotel and with that price tag.

The feeling is that the breakfast which I paid for was designed intentionally to get you spent more as it wasn't mentioned on booking that it's only a daily $30 in a super expensive restaurant. (Simple cappuccino is $19 without a tip). Staff at the reception and restaurant are not friendly or willing to help.

The staff was very knowledgeable and helpful with identifying attractions that my family might enjoy. They also did a great job of explaining the amenities available at the hotel. Location was perfect to access all of our trip destinations.

The price of breakfast was not worth it. Parking is only accessible through valet services. Nothing else to gripe about. Unless you plan on using all the amenities, it may or may not be in your interest.

The hotel facilities and location was good.

The hotel charge car parking at a very high rate of $79 per night for in-house guests. This is absurd. I can still accept a reasonable amount for parking, but charging the same rate as for an outsider is absurd.

The room was big and spacious and we had a very beautiful view of the city at night.

We requested for a later check out and was given 1:30 p.m. Then, when our tour operator informed us of our return timing of our morning tour, I asked for an extension of the later check out time to 2 p.m., but the counter staff very sternly rejected my request. On the day of our check out, we rushed through our washing up to reach the counter by 1:30 p.m. but there was a long queue of guests in front of us checking in. By the time the counter staff processed our check out, it was around 2:10 p.m. Wouldn't JW Marriot, being a top class hotel, allow for some flexibility in extending our check out time by 30 minutes?

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 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.
