23-year-old returning to Madrid, looking for accommodation

Hi there! My name is James, I am a 23-year-old student from Germany. I move to Madrid on Tuesday, October 13th, to begin a Master's course in Alcobendas.

I am searching for accommodation (single or shared accommodation) in the centre of Madrid, ideally as close to Puerta del Sol as possible, for at least 8 months, possibly longer.

I have lived in Madrid before. I spent a semester there in 2013, so i know the city quite well already. I am bilingual in English and German, and I also speak fluent French. My Spanish is good enough, but I hope I can learn more while I am in Spain. I would prefer Spanish flatmates for this reason, but I am otherwise open to any nationality.

I am very experienced in flat-sharing and living abroad, and I like to think I am easy to live with. If you live in the city centre and are looking for a flatmate, send me a message!
