I stay in a variety of hotels....this hotel is lovely and the rooms are well appointed. To my surprise, in the fitness center is a note: We launder your clothing for free!
I only packed one workout outfit and as such was really pleased to take advantage of this offer!
What a nice stay and pleasant surprise!

love the set up of this hotel with all the rooms facing an inner courtyard. theres a nice bar in the mezzanine and the service to your room is great if you need anything extra. my key card through the app didnt work which was annoying but not a deal breaker.

Great Hotel in a Great Location

I recently stayed here in December 2018. The room was large with (2) queen beds, dressing area, and huge bathroom. And the view of the city was awesome! We had the breakfast buffet both mornings....great staff, excellent food! It may be a little pricier than other hotels in Union Square....but definitely worth it!

Excellent hotel with great service

The JW Marriott may not be the most fancy hotel in the city, but given the price I paid (under US$200 per night), I thought it was great value. I had initially booked a standard room for one night, but needed to extend my stay for another, so I wrote in to front desk to ask if they could extend my booking at the same rate (the published rate then was much higher). Not only did they accede to my request, they even upgraded me to a studio suite as I was celebrating my birthday! Thank you so much Elizabeth! You were extremely helpful!

At the property, all the staff I met were very friendly. Cynthia at the front desk checked me in, and volunteered suggestions on where I should go for breakfast. I love her energy and positive attitude!

When I was checking out, I needed help from the concierge, and waited in line for a bit. One of the front desk staff saw me waiting and came up to offer help. Unfortunately I didn't get her name, but I remember she's originally from Florida, and she helped me check a couple of things regarding my trip to Yosemite.

I loved the room that I was upgraded to. It felt very residential, especially the bathroom. I was a little surprised that they didn't provide bathrobes and slippers, but I called housekeeping to ask for one, and got it right away.

Location of the hotel can't get any better. I faced the same issues with parking as everyone else, but unless you're parking during the day itself, there's plenty of street parking for free around the hotel. In fact, I managed to park literally right outside the hotel for free from 4pm to 9am.

Stay in San Francisco

I stayed in the Marriot for a conference in February. The place is bueatiful and we had great service from leaving our car with the valet to the nice bellman who took our luggage to our room. Check in was smooth, our room, clean, comfortable bed and shower with a double shower head with made for a great morning massage. The bar was comfortable with lots of couches for comfy drinking and relaxing. I loved the gym, it had all the free weights I like, a few weight machline along with elliptical and my favorite, the spin bike. There was even a separate area for yoga. The the towel warmer was a nice touch! The hotel was within walking distance of China Town and Northbeach and bus/ trolley lines. We had such a nice relaxing time, would definitely stay here again! Great staff, my friend forgot her passport in her room and security was able to find it and kept it safe till I picked it up, shows honesty and concern for guests.
