Looking for a bedroom and nice flatmates to live my dream! :D

Hi! I'm Bea from Rio de janeiro, currently living in Lisbon - Portugal.
Two years ago I went to Berlin for the first time, it was my first trip by myself, backpacking in a new continent, I fell in love with the city. Also went to Denmark, Amsterdam, Poland, but my heart is in Berlin! So I came back to Brazil decided do finish my university, save money and come back to live in the city that stole my heart!
I recently graduated in Social Work at the Federal University of Rio, last year I worked at the Olympic and Paralympics, hired by a british company to represent Samsung at the Athlets Village, they payed me very well so I payed a German course (that starts on the 6th of March) and my classes goes till the end of June but I intent to say more after that anyway.
So I'm about to make my dream come true! :D
My flight to Berlin is on 28th of february and I intend to move to my future home on the 1st of march (cause I'm gonna head there too late at night on the 28th). I need to find a good place to stay, with good friends to share some good moments together! (=
I'm travelling all the time is possible, I'll have classes from monday to friday but I might be travelling around at least one or two weekends, but the time I'm at home I'd like to have people with good energy around!
Email me for more informations if you want!
Thanks in advance
