This is a terrific place to stay in San Francisco. We were a family of 3 and my parents for 3 days and after that just 3 of us. It's a bit tight for 5 people but doable. The beds and the pull out mattress are very comfortable.
We were visiting family in the neighborhood so I already knew it very well. But for those who would like a calm and green place to stay while taking the BART or driving to different sites, Glen Park is a really good option. Jon's place is exactly as advertised. It was impeccably clean and to keep it that way we were sure to follow his very reasonable rules. Everything in the house is new and high end. The deck and garden are a dream - I loved sitting out in the sun and working on the deck. There is a lemon tree and flowers that make the garden very pleasant and peaceful.
In terms of transportation, it's a 15 minute walk to the Bart with a short but very steep hill at the end. Check-in and entry to the house went perfectly because there is a lock with a code. Jon is very attentive. The code reset and I couldn't get into the house. He responded to my message almost immediately and was able to reset the code remotely.
We definitely will want to stay here again!
