I loved staying at Peter's studio and I would stay there again. It is spacious, beautifully furnished and the bed is absolutely amazing. I especially enjoyed the patio on sunny days when I was able to work or do yoga or just read. And a vintage record player was a very nice touch. I stayed a month in this studio and the only issue I had was the lack of kitchen (although small fridge, coffee maker and microwave proved to be very useful). Just to be clear - Peter was fair and he warned me about it knowing I am planning a longer stay. I just missed it more than I thought. I also liked the location, it gave me an opportunity to explore Inner Sunset, however you should be warned that unless you have a car, you will need to walk quite a bit daily to get to shops and restaurants or to catch public transport to get to town. Or you can just get uber/lyft, it is really convenient. I personally didn't mind the walking, I actually enjoyed it.
Finally, Peter was easy and quick to communicate and was always very accommodating no matter the issue.
