Hey I live in San Bruno and as long as she stays south of the freeway she will have sun all the time lol
Really it s like a cut off for the fogg for some reason...
She can probably get a 2 bedroom for 1800 around here and btw living closer to the airport is actually not bad ,just stay past the railroad tracks and you are good to go. I live right off of El Camino around the corner from "the avenue" which is a small san bruno downtown walking shopping area ,really san mateo avenue ,and it s great! Love the mentioned shopping,walking everything on hand facts and it s safe! I walk here all the time with my little daughter and no problems at all!Very friendly neighborhood!
In my opinion San Bruno is the way to go and bart is right here so she can just hopp on that to go to work...

good luck for your friends housing search
