We were concerned about the Bayview area after hearing a couple of negative reports from Bay Area locals. However, we had an amazing experience in our short stay - and it was the people that really made it amazing. We were welcomed into a local birthday party as we wandered down the street, given a lift to a local event by a lady who saw us pushing our stroller up a big hill, had great time with other families at the local parks, and engaged in philosophical conversations by random strangers. Having said that, I'd still recommend not walking the streets at night as there are some shady patches here and there.
Scott and Jen were great hosts, answering questions with alacrity and going the extra mile to find things out for us. They gave us as much space as we wanted while also welcoming us to connect with them whenever we reached out. The space was super clean and comfortable and we felt really at home. If we are back in San Fran we wouldn't hesitate to stay here again.
