You gotta rent this appartment!!! Definitely... Trust me, as a young man who meanwhile likes the calm and quietness but also the life of a neigborhood. Len's place is perfectly located at the junction between many point of interests : Castro, Hayes Valley. Plus, really convenient to go to Marina northbound for fresh air over a cute little harbor with beautiful green spaces. You catch the 22 few doors away and you'll get to the bus stop on the same street... Many nice bars and good restaurant (including our beloved "Kitchen Story" which mixes thai and californian food on Sanchez St which is located couple blocks away...
Above all, Len is a really organised owner with good guidances with a file with everything you need (wifi, laundry, supermarket, etc etc) and he is always tuned to bring his help!
It was really nice and so pleasant to stay in his place with such good conditions.
So, please GO AHEAD! You woudln't be disappointed. Kind of the perfect place downtown...
Enjoy!
