Bar and event experience
Reviewed 5 days ago

We recently had an event to attend at this Marriott, and having arrived early we decided to sit with friends at the bar. We had checked out two other bars across the street and decided they were not very inviting. This bar is open, modern and airy and the waiter was extremely pleasant.

We had drinks, cheese plate (excellent array of cheeses with fruit slices, breads, etc.), chips with guacamole and salsa (best tortilla chips I've had in a very long time and excellent salsa) as well as their Greek flatbread. That, too, was tasty. None of this was inexpensive, but it was very enjoyable.

The final joke was on us, however, because the same appetizers were free downstairs at the event which started earlier than was listed!!

Hotel feels outdated despite its recent renovations, staff is reluctantly helpful. Bed is great. Clean. Quiet. Great location. The executive breakfast leaves a lot to desire. I expected more from a supposed-to-be top of the line hotel.

We are platinum members and were really shocked by this JW. We had asked for a quiet room and if this was quiet, I would not want to see the other rooms! I understand the hotel is near Union Square, but I expected double pane windows from a JW. I have stayed at other Marriotts in big cities and understand there will be some noise - but this was ridiculous. I have not slept all night, it literally sounds like you are sleeping on the sidewalk with drunk people shouting throughout the night. I mentioned it to the front desk and they said, yeah - we know, they are considering upgrades. Well, until that happens - we won't be back. Beds could also be upgraded. Good proximity to Union Square.

Another Visit to San Francisco

Another stay at the Marriott Union Square. We stayed here a few years ago and had a great time so we decided to stay there again. First off, the location is perfect for sightseeing. Many attractions and restaurants are within walking distance. The hotel staff is very helpful and will make suggestions mostly based on personal experiences. The rooms are clean and well-appointed and the housekeeping staff is excellent. We will probably stay here the next time we come to San Francisco in a year or two. It's one our favorite cities to visit.

Comfortable and convenient but the service standards need to pick up

We are a family of four and had booked two rooms at the JW Marriott in Union Square.

The hotel location is fantastic, walking distance from Union square. The rooms are large and well appointed and we had access to the concierge lounge on the top floor for breakfast and snacks. The lobby area on the third floor is very busy and can get crowded.

As a regular guest at various Marriott properties and a Gold Marriott Rewards member, my expectations from a JW tend to be higher and hence they got a 4 star review. The check in process was a little slow and despite multiple requests (starting two weeks earlier, at the time of booking) for two adjoining rooms, to my surprise we didn't get what I had asked for. I wasn't told that at check in and only found out when we walked into our rooms. On calling the front desk I was told that while they had my request on file, the hotel was full and they could'nt meet my request.

Since we were staying for four days, I asked them to change us as soon as something was made available and was told that I would need to call back the next day and keep checking with the front desk.

I did so the next morning and was still given the same answer. I did inform the "At your service" concierge that it shouldn't be my responsibility to keep calling,as they have my request on the system and that I expect them to keep me informed. It was only when my request was handled by Jeff from and based on his personal intervention and follow up, did the matter finally get resolved.
