German student looking for a room for 4 months

I'm a Master's student from Germany and will start an internship at the Goethe Institute Glasgow in mid-April. I'm looking for a room or small apartment for 3 to 4 months, starting either 1st or 15th of April. Glasgow won't be my first stop abroad. I have lived in Brussels and Madrid, and I love to live together with other young people from anywhere in the world. In addition to English and German, I speak Spanish, French and a bit Italian. I'm looking forward to all messages.
