Communication with Jason is excellent, he is very friendly and helpful. Right at the entrance there is a great array of maps and travel books for guests. There are no bars or other noisy neighbors at night near Jason's home. I stayed for over a week, and the house is always clean, the bathroom is spotless. The fridge is stocked for guests with eggs, juice and yes, cookies are sometimes available! Two streets up on Mission there's the best Mexican food there is in town.
Check-in and check-out is straightforward and Jason is flexible. I left my bags to explore the city on the last day and with good communication, the check-out was easy. Just notify Jason by text of your plans. Jason is a great host and I would recommend his home anytime for your next visit to San Francisco.
