Noisy
After being wowed by another hotel in the starwood group we decided to book this hotel for our first night in San Francisco. We wish we had the same elevator noise problem others on this site have reported on, at least then it may have been intermittent. We stayed on the 8th floor and our window directly overlooked the a/c's water systems for the whole building which was exceptionally loud and could still be heard even with ear plugs in. So even with the heavenly bedding (amazing) there still was not a lot of sleep to be had.
Overall the hotel is in a great location within walking distance to union square and lots of great shopping and has decent sized rooms. One other plus I can say about the hotel is that it is the first room we had on a month long trip with a decent hairdryer.
We moved after the first night to the HI Express at Fishermans wharf which was quieter and better value for money.
