Seeking room (or studio) in San Francisco

Responsible female, 29 years old, no pets, non-smoking. Looking for a room in a shared house (also open to low cost studio/SRO units). Ideally with private bathroom, between $1,000 and $1,400, and relatively close to Caltrain or 101 (Dogpatch, Bernal Heights, Noe Valley, Mission areas). Looking to move to connect with more people and jump in a few soccer leagues. Independent but enjoy catching up when roommates are around, and cooking for friends or playing some guitar now and then :) Flexibility on various factors depending on fit!

Many thanks in advance for any leads!
