Federico and I, two Italian guys stayed at Kurt's place, a really charming house, very well decorated with several pieces collected all over the world. The backyard is so cozy too.
The house is centered in Bernal Heights, a residential and quiet area, not exactly a tourist spot. However, u can easily take the J train (a sort of light subway) and buses to get quickly to other neighborhoods.
Unfortunately, we didn't have the chance to spend enough time with Kurt, but he seemed a really nice guy, considerate, respectful. Overall, an interesting person. He made us feel like being at our place ... also because we were usually on our own at his place ;D
