We had an amazing time in San Fran. Vivian was an excellent, professional host. Upon our arrival, Vivian showed us around and gave some great tips for the city. Although the apartment wasn't super close to the city, the buses are excellent in San Fran so it really wasn't a problem. The apartment was beautiful and clean with a super comfy bed and full kitchen. I would recommend Vivian.
One thing to mention though if you are a light sleeper - there is a fair amount of noise every morning from loud footsteps upstairs. Earplugs do the trick.
Thank you! we will be back :)
