Young professional seeks a double room

I am 26 years old, I'm freshly graduated and I'm currently living in Southampton for my first job. I'm looking for a room from mid April to the end of the summer. My plans though are likely to change, and I'll need to stay longer.
Even though I'd prefer to have roommates I'm also interested in 1 bed flats.
I'm sociable but not loud, I love joking, and I can't wait to discover Southampton. I have a lot of interests, so I can get on well with anyone. I was hosted by 4 different British families in several study holidays many years ago and I proved to be tidy and respectful. I was recently hosted by a lady in Lymington who appreciated my politness and was really fond of my cooking;)
I'd like to find roommates that don't mind socializing (I need to practice my English costantly:)) and that enjoy some... humor.
I like tidy roommates that are not loud (not too much:)) but I can overlook that if the environment at home is sociable:)
