Our stay with Marie was wonderful. The set up is a 2 story one family house in Diamond Heights. Parking is free and relatively easy to deal with given SF parking rules.
There are 2 small but comfortable upstairs guest bedrooms that share a common wall - and there is one shared bathroom. We stayed 4 nights and there was another couple for the last couple of nights. This was our first experience at a place with a shared bathroom so we were a bit nervous, but it was not uncomfortable.
Marie serves an amazing fruit filled extravaganza breakfast (with eggs, meats, cheese. breads upon request) for a nominal fee. She is very informative about greater SF and a pleasure to talk with.
