I'm 23 years old, I'm an erasmus traineeship student, I'm looking for an accomodation in lisbon. I would like a single room

I'm a nice girl, I'm looking for a student room in Lisbon, especially near Marquès de Pombàl. I'm ok with 2 or 3 flatmates, and I'm looking for a single room. I like student room in an University dorm, but I'm open also to a room in an house to share! I will be in lisbon only for two months for working in a laboratory in the Institude of Molecular Medicine ( IMM instituto de medicina molecular ) during an Erasmus traineeship program.
