Charlie's place was wonderful. Great location, comfortable, a nice back patio/gardent most of all, the hosts were incredible. Charlie and his wife, Barb, were very welcoming. Charlie is a docent at the SFMOMA, so offered to take me on a little tour there. I didn't have time to do it, but what a gracious host! Some of my best experiences traveling have been because of the host family I have stayed with and this is certainly true of Charlie and Barb. They seemed happy to give me my space to do my own thing and were also warmly welcoming. I was their first guest and they seem excited to have people visit. They are big travelers and speak many languages. I think they would be ideal hosts for international travelers wanting to get to know SF.
