21 year old girl looking for a room in Madrid, maximum price 300 euro per month

Hello you all! I study journalism in Prague and I am gonna stay in Madrid since September to the end of January thanks to Erasmus exchange. I am openminded, tolerant and adaptile person, who loves travelling, reading, culture (especially the undergroudn one), creating, freedom and what I love the most is whole life with all its open doors! I would prefer to have my own room - even with really little one, but although I am very sociable I also need my privacy a loneliness sometimes.
