Jason's place is a great and affordable private room experience in the Mission District. The rooms and entrance to the home have sturdy locks - and I always felt safe in the immediate surroundings of the home and in the home. The area is incredibly walkable (very flat). For visiting other neighborhoods, uber/lyft, Muni, or renting your own car would be great options depending on budget and what you're interested in.
Jason had plenty of tips or suggestions for fun things to do in SF. He has a ton of guides/brochures like any hotel would, but it was pretty awesome to see in an AirBnB. That info in addition to his local knowledge was really nice to see. It's clear he cares about his guests experience in the city and not just his home.
The house has 4 private rooms for rent on AirBnB. So, naturally, you may run into other guests during the stay or hear them talking in the next room or walking throughout the house. But it really wasn't an issue. He provides disposable foam ear plugs in case of any noise is an annoyance while sleeping. Another thoughtful feature of Jason's hosting.
Overall, Jason was a perfect host. Communicated in a very timely manner throughout the process and was very detailed and clear in any explanations. In fact, I would expect him to handle any issue before or during a visit better than AirBnB's support center would.
It was a great experience overall - and I would suggest his home to anyone interested. The mission district is great for younger people and people who want lots to do within walking district.
