I'm a 21 years old boy looking for a shared flat in Cologne

I'm Carles Feilen, a student currently living in Spain that next year is going to the University of Cologne. I'm looking for a flat for the first semester, from October until March. I'm 21 years old, responsible, social and excited for living new experiences and meeting new people. Moreover, me and my family have a very stable financial situation and we can assure responsability and puntuality with the payments.
