Loved, loved, loved this hotel
Stayed here this month (Feb 12) for 3 nights. We loved every minute of our experience at this property. We arrived in time for the wine hour (complimentary - and none of those sissy little eye-dropper wine glasses - these are the real deal!). Spent 2 days doing as much of SFO as we could fit in, including a superb dinner at Jardiniere which the doorman raved about.
The staff were fantastic - from checkin through doormen, porters and the concierge desk - everyone was friendly, helpful and seemed genuinely pleased to see us and help us out. 
The room was great - best beds I've encountered in my 2 weeks in the US (though almost needed a step-ladder to get onto it - I found just kind of falling over worked best!). The nautical theme is cute and consistent throughout the property.
We got an excellent rate though parking was pricey - but I suspect that it's pretty standard for the area. 
Easy walk to Ghiradelli Square, cable car stop literally around the corner, and 4-5 blocks to Pier 39 - you can walk or take the street car. The teens did the bike ride over the Golden Gate to Sausalito - bike rentals are in the Cannery immediately adjacent to the hotel - very safe and loads of fun.
I'd highly recommend this property as really enhancing the overall SFO experience.
