Looking for an all girls room July1 to Aug 30 in Lisbon

hello!!! I am looking for an a room/ apartment to stay in between july1 and the end of aug while doing my internship in lisbon. I am clean and sociable and a very open minded person. I want to experience the city with people who are fun and open to adventure. I am on a low budget so I want something cheap a maximum of 500 euros. I am not very picky so long as my roommates also are clean and are girls that's all i need. and somewhere close to the university of lisbon preferably.
