Lynn was great, I had no problem getting in or leaving the keys to get out. I ended up staying for 3 months. Waking up with the sun and having a stunning view made the experience wonderful. It's probably better suited for a shorter-term stay given the kitchen and furniture layout.
The location is definitely the best given that it's accessible to both the Mission and Castro while still being on a quiet side street. Perfect spot for someone staying for a few days to a week to set up as their HQ to explore the city.
