No complaints - wonderful!

We have absolutely no complaints.  Great location, friendly service, good breakfast buffet and roll-away actually suited my teen-aged daughter!

Great location in SF.

Pros: Close restaurants
I loved the location of this hotel. Very close to Union Square and plenty of places to within walking distance. If you want to save a little money on parking there is a parking garage across the street from the hotel. Nice hotel, staff and comfy rooms.

A great experience you won't regret!

Nestled a few blocks away from Union Square, the JW Marriot was a comfortably luxurious stay. The room itself was well kept, clean, and elegant. With an extremely comfortable bed and a great view, we enjoyed what time we spent there. There are some cable TV channels available if you are feeling lazy, which was great when we were tired after a long day and just needed to relax. The shower, however, was a bit on the small side, which was odd. The dining options at the hotel were delicious, but very expensive for what you get. The fitness center is large and clean, but the business center is way too expensive to really utilize ($0.45/minute just for internet). The elevators are fast and large, so you'll never have to wait long to get to the lobby or ground floor. The staff goes out of their way to help, making you feel like a VIP. Overall, the service was top notch. The location of any hotel in San Francisco is imperative, especially if you don't have a car like us. While it could be closer to Union Square (and thus the Powell St. bart), the walk to the nearest bart is an easy one. In addition, there was usually a cab waiting at the hotel thanks to how slow business in SF is right now. Overall, this hotel was a pleasant one. Though it didn't blow me out of the water, it was a fine stay that I wouldn't mind repeating.

Nice but Expensive

Our stay was fine, the room comfortable and clean. The concierge service was excellent--perhaps the highlight of our stay. Our only concern was the price, which we considered a bit high even for downtown San Francisco.

Anniversary in San Francisco

Overall, my wife and I liked this hotel. But, for a flagship JW Marriott property, we were not overly impressed. The hotel has a very modern styling with no greenery in sight. The location is 2 blocks from the trolley, and 5 blocks to BART. Shopping at Union Square is 2 blocks away. Parking at the hotel was $45 per night; acroos the street is $15. All restraunt recommendations and tours made by concierge were outstanding. Our room was clean and bed was comfortable. Again, very modern. The seperate shower was very small. Two seperate sinks would be nice.

Good hotel, but there is better.

On my last stay in San Francisco I stayed at the Marriot on Market st. and I'd reccomend that hotel over this one. The location and overall hotel was just a little bit better than the JW. The rooms are little bigger, there is a big and beautiful lobby with a starbucks, the muni is right outside the hotel, and the bart and cable car are about a block away. At the JW the complimentary town car is nice, but only available 7-930am and 530-9pm and it's on first come, first serve basis, so don't count on it. The bed was amazing! the tub in the bathroom is nice and big. The nights were quiet, I didn't hear any traffic on the street. The fitness room is a decent size with a variety of equipment. My only complaints are the distance to all the transportation systems (about 4-5 blocks) and I never got the replacement water bottles that I asked for.
