Overall, I really enjoyed my time in the Inner Richmond neighborhood. I just moved to San Francisco and was staying in Ching Ho's place transitionally. I had some problems at check-in - my key did not work on the front door and my room key had been taken by another tenant, but the communication via the Airbnb app with Victor and Ching was excellent. Ching Ho's mother gave me a new key to enter the building and Victor advised me on another room to take and told me that I could shift to my actual room in a couple of days. They worked hard to accommodate what could not be planned for.
The abode was just wanted I needed - a place to sleep and get ready for work. There are multiple rooms and tenants at any given time (up to 5-6) and two bathrooms which was more than sufficient. Everyone keeps to themselves for the most part. There is a kitchen that you can use to prepare meals but I did not use it. I got dinner on Clement Street most evenings (Taqueria Los Mayas is a favorite).
The place is clean and there are plenty of towels. I had a car and one of the big drawbacks was that there is limited street parking and the city patrols and tickets mercilessly. There is only two hour parking M-F 9am-6PM if you do not have a zone permit, and I got two parking tickets in the six days I stayed at this place. Be forewarned if you have a car. Try to find somewhere farther away to park to you are not ticketed or take your car with you M-F.
All-in-all, I would stay at 311 4th Avenue again.
