single/shared room wanted central San Diego starting November

Hi, I am Charlotte (26) and it´s my second time staying in San Diego as a research scholar. I am looking to rent an affordable single or shared (female only!) room in San Diego from 1. November 2018 until at least 31. January 2019. Preferably the location should has good connection to the public transportation (busses/Green Line) since I will work at the regional water board near Qualcomm Stadion and SDSU (e.g. Point Loma, OB, MB, Hillcrest, North Park, University Heights,..). The maximum I am able to pay is 600$ a month. I appreciate all kind of help. I have plenty of good references as a roommate and have always shared apartements during my program. I love to share travel stories, climb, hike, beach time and a glass of wine at night. Friends would describe me as hard workinh, honest, outdoorsi and social. Send me a WhatsApp (0049)1745454680; e-mail or give me a call ----/-------
