19 year old student from London looking for a home within the ring of Amsterdam

Hi guys, 

I am looking for somewhere to stay long term, and time is running out and I really need to find something! I am a 19 year old student, born in London and raised in Spain. I am currently in my second year of my International Business Bachelors. I would like somewhere close to the city center, that would be perfect! My budget is 750 including utilities and would like a long term stay. I am very friendly, funny, and also respectful. I am also very tidy and clean (even though many people say this). I love doing sports and playing games, and having a drink from time to time. If you have any available places please let me know!
