Charlie is an exceptional host and the flat is a great place to visit San Francisco. Everything in the flat is perfectly clean (you have to do your part by taking of your shoes and keeping the shower clean). I was in San Francisco for a conference and I also bought my camera equipment. Charlie gave me great recommendations for photo viewpoints and restaurants. The flat is also really close to Downtown. Taking an Uber rarely takes you maximum 20 minutes to get to any of the famous sights. His information on public transport was also really helpful.
All in all, it was a great experience!
