24 years old guy looking for accommodation in Stockholm

I am a 24 years old Swedish engineer guy that recently graduated. I am looking for a small accommodation and potentially a roommate/rommates. The accommodation should be located north-west of Stockholm, near Järfälla (less than 1 hour commute).

I am a calm guy with a lot of interests: music (I play the piano and some other obscure instruments), martial arts, programming, and more! I don't smoker, and I don't have any pets. I am social but still introverted, and I want people in the accommodation be warm and open for social events as well as respect each others' alone time.
