answer:k so for starters, look through my old questions (the very first ones are almost all about SF) bart is kinda expensive, 70 bucks a month for unlimited… and that’s how you’d be getting here from oakland or berkeley. oakland is not really safe but there are nice areas. i’d do some more research into that. being that you’re a 22 year old female, i’d be careful in oakland… just my opinion. noe valley is awesome! really pretty but super hilly from what i know of it… very much a family type neighborhood. there are muni lines that run there, so it’s kinda easy to get around. so many street performers… yes the warf has a ton and some are staples that are there all the time. some are also kinda famous (some musicians and the bush guy) city is bikeable… there are routes to avoid hills and SO many people ride bikes. i’m around your age, and female as well. i moved here in december and i am nooo expert but this has been my experience. this was the best thing i’ve ever done in my life. keep in mind that it is an expensive city. PM me if you want more info.
