Seeking for house or flatshares

I am an italian guy of 28 years old and I will start working in Koln from September 1st.

I am seeking for either flat or room, possibly not too far from the central station, available since September 1st (or date as close as possible to that one)

I used to live in share apartment during the last 4 years, for both studies and working purposes.
In particular, I lived in Sweden for a year, Moscow during 4 months and Venice during a year.
Then, I start working in Milan since last year and I have been living in a share apartment.

I think to be a cool guy, friendly and respectful. I like do and watch sports, meet people and go out with friends.

I will be in Koln on August 22nd and I will be available to check rooms/flats.
