We had an amazing stay at Jeff's place!
First, the shared garden was very tropical and unusual (in a good way!) for San Francisco, featuring wild parrots, hummingbirds as well as a lemon tree.
The apartment itself was very spacious, with good internet (~60 Mbps) and a spacious bedroom and living room. The location was also great, within walking distance to Marina.
Finally, and most importantly, Jeff was the best Airbnb host we ever encountered. He was very responsive and attentive to our needs, tended the garden, and surprised us with floral arrangements.
Can't wait to return! :)
