My husband and I really enjoyed staying at James' place! We have been to SF quite a few times, mostly staying in hotels near Union Square and wanted to get a new experience for this trip. We loved the neighborhood. Would highly recommend a visit to the sushi restaurant on Cortland Ave (Shokudou) during your stay.
The suite itself was charming and had everything we needed to enjoy our weekend and get a taste of living in a more residential area of the city (compared to being downtown in Union Square). James was also very communicative. We did not have any need to reach out to him during our stay, but he was very attentive to our experience at check-in and after we left. The only downside I would call out is the hill that the house is on (but hey, it is SF so this is going to be the case almost everywhere). The street dead ends on a steep upward hill, so would recommend meeting Uber/Lyft rides just a tiny ways down the street at the intersection where cars don't have to back down the steep hill to get out to save yourself some time.
