We absolutely loved California
We stayed two and a half months in Flip's apartment. Overall the stay was nice.
The apartment was quite spacious and luminous and had a beautiful private garden, which you could see from the living room as well as from the bedroom. The neighbourhood (Haight Ashbury) is very lively and is just a few minutes walk from Golden Gate Park, which is one of the best places in San Francisco.
On the other hand, I'd also like to point out a couple of details that we didn't like as much: first of all, the neighbours upstairs were quite noisy. I know this is not the owner's fault. Second, the shower head was mounted quite low and there wasn't much water pressure. Third, we had some problems with the toilet (cistern). And lastly the fridge was also a little noisy, especially during the night. But overall, we spent 2 lovely months in San Francisco.
