We were in SF for 3 nights, and as we had a car, it was great being able to leave it at the apartment and take public transport into fishermans wharf (train + bus = 45 minutes and they run very frequently) but then have it to explore other areas out of the city. So this was a huge plus!
The apartment was private, sunny, clean and well equipped.
Shops for basic supplies and public transport just around the corner, and the area seemed safe at night. We would definitely recommend.
