Great location - amazing views of Alcatraz and the bay, safe neighborhood, good food and drink nearby. Bill is a great, attentive host. Very nice house with top end counters and fixtures.
Russian Hill is a bit of a hike to the Financial District and Moscone, but in return you aren't stepping over homeless people in your doorway.
One note is that if you need the fourth bedroom it lies between the master bedroom and master bath in a not very private way (but with the best views in the house).
