Searching for a room in Helsinki, end of 04 / beginning of 05 15

Hei,

I'm searching for a room in a shared apartment in Helsinki up from the beginning of May (or a few days earlier), an end of my stay in Finland is not planned in so far.
But maybe a few things about myself first: I'm a 35 years old male from Germany (so far I've spent most of my time in Hamburg and Berlin) and have lived in several shared apartments before (in different countries with male as well as female flatmates), so I guess I'm quite experienced with this.
After studying literature and philosophy I'm now trying to get my first novel and short stories published but I still need other jobs to pay the bills.
At the moment I'm working for DHL and most probably I'll do something like that in Finland, too.
When at home I do writing or reading most of time (or learning languages, which is one of the reasons to move to Finland), so I'm a rather quiet person and quite - well, tidy... I'm not completely sure, but very clean. I like music but use headphones most of the time anyway.
I have no problems with pets, though I have none myself, and don't mind smoking - actually I like it myself, but I've lived in non-smoking apartments, too, without problems (though a balcony or something might be good if possible)...
What else? I will most probably not take many things with me, so I need not too much empty space, but on the other hand the kitchen for example has to be there already.
Well, if you have any more questions, just ask! Hope, to hear from you,

Thomas
