Charles and René were absolutely fantastic hosts, and certainly the best hosts I've ever stayed with. Their warm and comfortable home had everything any traveller would need or want (fully stocked fridge, snacks, great water pressure in the shower/tub), and Charles and René were so friendly, warm and generous, going above and beyond to ensure we had a great stay, and sharing their experiences as old guards of the Mission district. Their 'house/neighbourhood guidebook' was such a treasure trove of things to eat/do!
Their garage is a little narrow, so do careful if you're driving a larger car (we drove a mini SUV and it was a little tricky getting the car in and out). All in all, we had a great time -- largely in part to our lovely hosts. We hope to stay here again!
