Looking for accommodation in Poznan, single Japanese

I was born and raised in Japan. I used to work for fashion company.

And now I am Japanese teacher at the moment just online.

I came here Poznan for learning Polish language in UAM. I would like to live in Poland for a long. 

Now I need a room for studying and relaxing. But I am struggling with finding it.  I'm staying at hostels and some temporary apartments but I want to settle down.

I am so neat and tidy. I like cleaning. Not like party person. No loud music.

I don't bother you at all. So please let me have a room. Thanks
