We really enjoyed our stay in Dennis and Tiu's home. We had very little interaction with our hosts but there was an instruction manual and interaction was really unnecessary. Everything was very clean and in great shape. It is s a non smoking house and there was no smell of any smoke. They had wine for us and "check in" was easy. The home was quiet and lovely, the neighborhood was good (stunningly beautiful, in fact) and parking was easy. Easy ride to San Francisco.
