23 year old guy, looking for accommodation in Amsterdam

I'm an easy going 23 year old guy from Germany starting a bachelor programm at the UvA in September.

I dont need much space and I'm a very clean person, maybe a bit ocd ;)

I'm looking for an affordable room in a shared flat for up to 500-600 euro maximum, the less it cost, the better of cause ^^

My boyfriend already studies at the UvA and lives in Amsterdam for about a year now, so I know the city a little little bit already. It would be lovely to find a place near the University or the Centraal station, but that might won't work out financially... anyway! I'm openminded and really easy going and looking for flatmates who share these characteristics :)

Please do not hesitate to contact me if you have any accommodation to offer or know someone who has! :)
