Great hotel in San Francisco
Reviewed 5 days ago

Lovely building, friendly and helpful staff. The room was very comfortable with a big bathroom which had a huge shower. It was also quiet noise wise which isn’t always the case in US hotels. There’s plenty of restaurants nearby. We had a great stay.

Elegant and comfortable
Reviewed 1 week ago

We stayed here for 4 nights and found all the staff to be pleasant and helpful.
The rooms and public spaces were spacious and elegant and we really enjoyed staying in our king room. The bathroom was well appointed and the bed / pillows were very comfortable.
The hotel is well placed to access the cable cars, hop on hop off buses and public transport. We walked everywhere and found it very easy.
We would happily recommend this hotel.

Nice hotel but average by JW standards
Reviewed 2 weeks ago

I spent last night at the JW in San Francisco and overall enjoyed my short stay. As a Titanium member they upgraded me to an "executive corner" room on the 17th floor. The bathroom was updated and featured Grohe fixtures.

The room was not a suite but had a feature that I thought was great-- the windows actually opened and since it was a corner there were two sets of windows which when opened created a beautiful natural breeze with the cool ocean air filling up the room.

The lounge is on the 21st floor and had a nice dessert spread and a decent continental breakfast.

This hotel is nice but it is older and not quite as posh as the newer JW's (think Austin, TX). The room rate at this property is also quite high but that is a function of location location location.

Personally, I prefer the St. Regis in SFO but the JW is a nice alternative. They also had super comfortable bed with high end bedding.

I'd recommend staying here but don't expect to be blown away.

Great Stay

Two night stay was wonderful. As a Titanium member, they acknowledged it and were welcoming. They treated my wife well as I was late to arrive. An upgrade was available and the room was very comfortable and modern, with a great bathroom. Thank you Jeff P. for the nice welcome note and special welcome gift! Great location. Will stay again when in San Francisco.

Location, Location, Location!

My husband and I stayed 1 night and we couldn't have asked for a better location to walk around and shop at all of the union square high-end stores. This area was great for walking to dinner and bars. We greatly enjoyed our stay and would come back again. Surprisingly, I preferred the room and the views of SF at the Marriott Marquis in Union Square more than this JW. None the less we had a very nice stay!
