A couple who are both interesting, entertaining and informative about anything you would want to do. We were welcomed with wine and cheese, and had excellent coffee every morning, and yes, the warm croissants .... either loosen your belt or just enjoy.
At first I didn't think we could sleep with all the traffic, but I was wrong, it didn't interfere at all. However you have to open them for some air now and then. There are 3 flights of stairs, up and down, and it gets you prepared for the streets of San Fransisco!
All in all, I found our hosts charming, helpful and with humor and we definitely enjoyed our stay. I do wish we had more interaction with their two most adorable small dogs.
