Hallo! Finding a room in Munich starting April 10 up to 3 months!

Hallo! My name is Tomas, Im 23 years old, Im Argentinian, and I have the Spanish citizenship as well. Im a really easy-going and peacefull person, like to share experiences as Im a native traveller and in this ocasion Im going to Munchen in order to see my old Rolfing and Streching teacher who is now living in the city! As i will be practicing twice or three times a week and I will be working as well I don`t expect to be much time on weekdays, although as I almost always cook my dinner, you will happily see me in the kitchen! Also I would definitely love to share some time and experiences on weekends! Im looking for a place to stay for 3 months starting from something like April 10, and for that I will need to rent a place where doing the Anmeldung is posible! Expect to hear about you, best regards!
