If you don't need to be near the hub of activity in downtown SF, you can't beat this lovely apartment. The place is immaculately clean, located in a quiet neighborhood, and the backyard even includes a hammock! Love the keypad system; makes everything so convenient.
Gustav was extremely responsive to communication and even though he wasn't home during most of our stay, he came back right before we left and allowed us to use his kitchen to cook food. He also recommended a few awesome off the beaten path spots to check out.
I highly recommend Gustav and his lovely garden apartment. I'd definitely stay here again if I were back in the area!
