Mike and Joann are terrific hosts. They had tons of good tips and advice at hand and they helped greatly in making my stay in SF as awesome as I could only wish for. The house is beautiful and the neighborhood is very clean and calm. Still, you can be anywhere in the city quickly, as public transport is nearby. It was quite hot during the second night, but that's due to the hottest day in SF ever and definitely not my hosts' fault. :)
Highly recommended!
