Had a great time in San Francisco at Mark's place! We used Lyft to get around pretty much everywhere (dinner, sightseeing, etc) and it was very affordable and convenient. Everything to see was within a 20 minute drive (if that). The house was clean and check-in was easy. The neighborhood is quiet, away from tourist areas and there's a Starbucks a few blocks away which was nice in the mornings. Would recommend!
