23 yo girl, looking for accommodation in Glasgow

My name is Laura, 23 years old and I'm an international student, from Portugal. 
I will be studying at Glasgow School of Arts for 5 months, as an exchange student. 
Therefore, I'm looking for a place to stay for at least 5 months, starting from September. 
I would prefer a room or a shared flat near the City Centre or in West End, and my max. budget would 400 ppm with bills included. 

I'm an easygoing person and I have shared a flat for the last 4 years. Would prefer to live with girls only. 
When I'm at home, I like to watch a nice movie, read a book, or just making a nice dinner with friends and roommates, and have a nice chat. Sometimes I also like to spend some time alone. 
I also like to go out, visit the city, or at night to have a drink with friends. 
Not much of a party person but wouldn't mind once in a while. 

I will arrive in Glasgow on 7th September.
