My husband and I absolutely loved our stay at Petite Auberge. It was so much nicer than staying in the big chain, over priced and impersonal hotels in San Francisco. We stayed on the lower level nearest to the breakfast area in a Queen room with fireplace and we loved it because it was nice and quiet. The breakfasts were lovely: pastries, bread, hot food etc. and the afternoon cookies were amazing- we were always looking forward to them! There are just a few things to be aware of:
1) the room might get a little hot in summer as I don't recall seeing an air con (we stayed in winter, so this wasn't a problem for us)
2) there isn't always someone at the front desk, however there is a phone at the front desk if you ever need to get a hold of them during your stay. We did not mind this at all!
Basically, If you're planning a trip to San Fran, Petite Auberge will not disappoint!!!
