Was greeted by Jason's mom; Jason was out of town; wonderful hostess, she made me feel quite welcome. The room was clean, spacious and bright. The immediate neighborhood was more or less residential with a bit of an industrial feel across the street on Folsom. But, just a few blocks away there is an vibrant scene with restaurants and cool night life. On the way back from my evening class I passed by a place that happened to have a free comedy night; totally random occurrence, but super cool. As a single guy, I didn't feel any danger walking at night; and free parking was pretty easy to find. That is a big plus in SF! All in all, I'd definitely recommend Jason's place.
