Our stay at Jason's place was great. He was very upfront about being out of town so he had his mother meet us and show us the place. She was very flexible and met us fairly late in the evening after communicating through texts; despite the hour, she was friendly and enthusiastic. The location is in a more "gritty" area of the Mission District but it doesn't feel unsafe and is a convenient walk to the BART and popular spots along Mission and Valencia streets, many of which Jason has documented for your convenience. We got the back bedroom, which was surprisingly large and comfortable for two people. All four bedrooms were booked while we were there but except for a couple of inconsiderate guests waking us up early, the place didn't feel crowded and it was easy enough to get into one of the two bathrooms. I should also note that Jason was quick to respond our complaint about the other guests and I was more than pleased with how he handled it. All in all a great stay and a great host.
