My wife and I stayed here for four nights on our first visit to San Francisco in September. We found this to be an ideal location just a few blocks from Union Square and only a couple of blocks from all three cable trolley lines.
The plentiful and delicious buffet breakfast had a different hot selection every morning and the complimentary cookies and the evening wine and snacks were a great touch, the latter giving you chance to meet your fellow guests if you wished.
We had a De Luxe King room on the top floor which was spacious and had a fireplace which we did not need to use as was hot and sunny during our visit but would be ideal in colder weather.
The staff were very friendly and helpful. The front desk is not always manned but not really a problem as you only have to go next door to the White Swan for prompt attention.
It is in an older building but did not notice any noise from other guests and no more noise from outside than you would expect in any city.
We thoroughly enjoyed our stay her and would certainly stay here again if fortunate enough to return to San Francisco.
