26 year old ex law student from Pakistan, looking for a room in Athens

I am looking for a room with a bed, wifi, and access to hot water. Beyond that it is a luxury. I need a place for three months at least ideally, since I have paperwork to complete with organisations in Athens nearby. I can speak Urdu and English and Punjabi fluently, and have spent the last three years travelling, working and volunteering in Greece with animal shelters, farms, and refugee organisations. I know Athens qjite well, having lived here for a few months a couple of years ago. I am easy going and chilled out, and in a long term relationship, but travelling mainly alone !
