I spent a month at Flip's place because San Francisco is somewhere I always wanted to expeirence, and had an absolutely wonderful time. The apartment I can't fault, It was clean, spacious and I can't state how nice it was to have a private garden, which is a lovely and sun trap that doesn't get too windy. The facilities are great as well.
You're right in the heart of the Haight, but just off a corner so it was quiet, so you're close to the action without any noise. I saw some other reviews speak about neighbours upstairs but that wasn't my experience and I am a light sleeper. If. you want to see true San Francisco it's definitely the area you want to be, and Golden Gate park is minutes walk away.
Flip was a great host, responsive when I had any questions (which wasn't much) and super flexible with my awkward flight times for checking in/out.
Would definitely recommend and definitely plan to come back again in future! Thanks again Flip!
