Jake and Scott in the JW Marriot are the best! Best bartenders, greatest experience, amazing service and personalized care. We enjoyed an evening getting to know these gentlemen and it was really cool. They even realized at end of night we left our coat and personally brought it to our room. Amazing level of personal care rare In this industry. Thanks guys, you changed our experience from4 star to five!

All JW's are not Equal
Reviewed 2 weeks ago

I have stayed at this property multiple times and love it! I will be returning as well as it's our annual SF place. I dropped it a star because the week prior we had returned from the Los Cabos property. Even though they are both JW's, it's like comparing apples and oranges.

On the positive side, the remodel is excellent. We stayed in a remodeled room last year but I had forgotten the beauty of the new shower. The color scheme is light and airy and very refreshing. The only thing I'm not sure about in the remodel is the pre-stained mirror behind the bed. It does make for good conversation, especially is you have guests come and visit.

Although service was not Los Cabos service, everyone we encountered was friendly and helpful. The Marriott strike was happening during our stay and all of the employees were professional and hard working.

As a platinum elite member, they gave us a great city view room on a high floor as requested. They upgraded our other room to a Jr Suite as we had acquired an extra relative to house. I really appreciate the upgrade and it made the stay much more spacious and enjoyable for the other room.

We had no meals or drinks during this stay. In the past, we have always enjoyed relaxing in the bar, but we did not get the luxury to do so this trip.

The location of the hotel can't be beat. It's easy access to everything and I like how the reception and bar are on the third floor. It offers an escape and respite from the busy city. I know there are many options in SF to stay, but we will always stay at the JW. It has everything! If you have a car, there is a much more affordable parking option right next door.

Wonderful visit to San Francisco always includes a great Hotel. The JW was 5 Star. All our request were met. Quiet floor, extra pillows, extra towels all delivered with friendly service. I look forward to booking the JW Marriott San Francisco for my next visit.

Worst hotel - Review by a guest who stayed in 67 nights in Marriott properties this year
Reviewed 1 month ago

First of all, let me tell you about my profile. I am a Platinum customer stayed in Marriott hotels for 67 nights this year alone. With Marriott for last 5 years.
Now coming to the JW Marriott SF, this is one of the worst hotels I stayed. Insulting staff. I stayed in this hotel from Oct 27-Nov 2, 2018. I arrived at the hotel at 4 PM, and the lady at reception says that Platinum guests are asking for late check-ins and I have to wait. Note that 4 PM is their standard check-in time. When I asked when will get the room, she says that she cannot say it. Ridiculous. By the way, I did my mobile check-in also before all this nonsense. Their room service is pathetic, and they skipped doing room cleaning one day even I am out of their green initiative. Forget about upgrading rooms for the platinum customer; they gave a place that don't have minimum requirements like a refrigerator.
They don't have happy hours at the lounge, and the only silver lining is their staff at the business lounge who are at least courteous. If you are going on vacation, stay away from this stupid place. There are better places near by. If you don't have options, God may save you!
