My boyfriend and I stayed at Ryan's place for two months and had a really wonderful stay. The location is the best part - right in the heart of the Marina/Cow Hollow/Pac Heights area, so a quick walk to Union Street, Chestnut Street, Fillmore Street, and the water, but also still quiet. Going into our stay, we were a bit worried about being on the ground floor, but found that it didn't end up bothering us at all!
The apartment itself is cute, spacious for a couple, and very well-maintained (though of course a bit on the older side, as many apartments are in the area). Ryan was also an exceptionally accommodating host - any time I reached out with a question or issue, Ryan responded and had a solution within minutes. For example, after a rainstorm, the front door warped a bit and became hard to close, and Ryan had a handyman in there to come sand it down within a couple of hours. I'd definitely recommend this place!
