This place was perfect for my short trip to San Francisco. The check-in instructions seem daunting at first, but they're actually really simple once you do them.
One highlight is the location—nicely situated between my work needs downtown and all the fun stuff in Mission/Dolores/Castro/etc. I walked most everywhere and safety was never a concern for me.
The host was also very attentive, checking in occasionally to see if everything was going okay. No issues ever came up, but I'm sure she'd be responsive if they did. Thank you!
