If you're browsing SF airbnbs, seriously, browse no further. Out of our 2 months of travels, Gregg's place was absolutely a high point. It truly made our stay in San Francisco. The house is beautiful, even more then the pictures show: everything from the kitchen to the garden is minimal but cosy and incredibly well conceived to be as practical and efficient as possible. He has truly made the most of his skills and space.
The location is great and so close to many wonderful restaurants, with a great view on SF hills that is especially great at sunset and sunrise, and that you can peek at from your bedroom's window. Gregg himself is lovely, very easy going and helpful, and makes great conversation and a wonderful host.
We hope to be back sometime. Absolutely recommended!
