22 yrs old student looking for a room in Barcelona

I live in Milan and I'm a 22-year-old architecture student. In addition to my studies, I do various jobs such as being a basketball coach, babysitter, or waiter. I will be in Barcelona from September to January for an internship. I am a sociable, friendly, and respectful person. I enjoy meeting new people and immersing myself in different cultures. I am a tidy and clean roommate. My typical day in Barcelona would involve spending the mornings doing the internship, followed by study sessions or other work in the afternoon. In the late afternoon, I would like to engage in sports activities to maintain an active lifestyle. Some evenings, I would go out to have fun with friends, while others I would spend at home with the other roommates.
Ideal room would be exterior, 550€ (bills included), with other 3/4 students, if there is a balcony or terrace it would be awesome.
