21-yo guy from Barcelona looks for roomates in Lisboa (March-July 2023)

I'm Roger, a 21-yo Biomedical Engineering undergraduate from Barcelona who looks for roommates in Lisboa for the spring semester. I don't mind what goes on in each room, but the common spaces being very clean and tidy is crucial to me. I speak Catalan, Spanish and English perfectly and I can speak some Italian and Portuguese. I'd like the shared flat to be a place in the center of the city, where we can peacefully study/work on weekdays and let loose and party whenever we all agree on it.  I prefer to live with people from southern Europe because we are much more alike.
