This is a lovely affordable apartment in the Portrero neighborhood. I was working at the base of the hill near Zynga and it was a nice 15-20 min walk.
Getting downtown via Muni would be easy as 20th drops right down to third where there is a stop. Coming from downtown via Lyft was a snap - 18th is an exit from 280.
On the plus side it was private, clean, well kept up, and comfy. I'd stay here again if I needed to be in the area.
There are several fun restaurants in walking distance (Plow, Mac Daddy, and Long Bridge Pizza are great). A couple of small groceries are up 20th a few blocks.
Things to be aware of - the house sits on a hill over 280. You can't see the freeway and I barely heard it (good glass). Also, as the house is about 2/3 up Portrero you will get a workout if you walk a lot (for me this was a plus).
It isn't a full kitchen, but with Microwave, Kettle, Coffee machine and Fridge it had everything I needed.
