Syl and Art's place is in a fantastic neighbourhood full of great bars, cafés and restaurants (we recommend visiting the Inner Fog Wine Bar on Irving and Lavash next door for some amazing Persian food!). Tonnes of public transport options nearby and very close to Golden Gate Park - walkable in under ten mins
My mum slept on the queen bed and I had the sofa bed which is fine for one person but you wouldn't want two in it. The kitchen is great and bathroom fully equipped with everything you need (some larger people may find the shower a little tight though).
The suite is fitted with lots of heating options for colder nights.
Syl was really helpful and allowed us to check in early and leave our bags in her house on departure day as our flight wasn't till late at night. She gave us lots of good suggestions for places to see and she and Art are both super welcoming.
