I live in Washington, D.C. but rent cars in San Francisco!
I use an automated system called StreetSmarts (www.streetsmarts.io) to give renters a superior rental experience while minimizing time and effort for both renters and myself!
The price is cheap and that is exactly what you get: a dirty cheap old car. It works and the pickup and return is ok. But the car is not how it looks like on the pictures.
Wouldn't be my first choice, you're better off paying an extra 10$ for a cleaner better car
