Neat guy, 22, looking for a room in Amsterdam long-term

Hey y'all! I'm a 22-year old guy, recent master's graduate in business administration.
I consider myself as a kind and neat tenant who doesn't create any problems. For the whole of the last year, I have been living in a shared apartment in Brussels (with another guy and a girl), so I already know what it is and how important it is to respect one's personal space. I'd love to make new friends though and to hang out with them from time to time. I can provide you with a recommendation letter from my previous landlord on demand. I would like to find a private room with registration possible and with a rental period of 6 to 12 months. Somewhere around Amsterdam. I would greatly appreciate if you could help (and if you wanna look for an accomodation with me - write me too)
