Intern looking for WG or studio apartment

Dear tenant,

My name is Ricardo. I'm 25 and I'm from a small town in the north of Portugal called Viseu. In 2014 I moved to Lisbon, where I lived for 6 years and graduated in law. Currently, I live in Vienna where I work at the Organization for Security and Cooperation in Europe (OSCE).In April I will move to Munich for a paid internship of 6 months (until September 30) in Unterfohring - Therefore I need an available apartment for the dates mentioned. I am available to stay as long as is convenient for you.
I am a calm, sociable person and really into sports; responsible for the preservation of spaces and used to living independently since I left my parents' house when I was 18.

I'm also a student of Political Science and International Relations - currently writing my thesis.

If it is in your interest to rent me the apartment/WG under the conditions you propose, I would like to know if it is possible to pass a Landlord's confirmation of residence - I have to register my address in Germany in order to receive the tax ID number.
I look forward to talking further with you and I am available to send you all the necessary documentation.

Thank you very much!

Best regards,
Ricardo Marques
