Seeking Housing in SF (potrero/dogpatch/mission)

Looking for an apartment in SF (lease takeover or long term) - we are a recently graduated couple, so looking for our own space not a room in a share.

Must be near caltrain/BART for commuting purposes, so we are looking at Potrero Hill, Dogpatch, SOMA, or the Mission (near either 16th st or 24th st BART). Looking to move in August 1 or August 15

Happy to be pointed towards any leads!
