I stayed with Frances and Dave for a weekend after a conference and they are some of the nicest people you'll ever meet. They went above and beyond to ensure my stay with them was a pleasant as possible and that i made the most out of my days in San Francisco. I usually use my bicycle as my main means for transport and when they found out they happily let me use one of the bicycles to get around the city. I had a walk with Dave around the neighbourhood and he gave me some great tips for breakfast and places to sit and do some light work. The bed was amazing and the views of the city are great fro the area. If I ever come back to SF I will definitely stay with them again! :)
