Renting house/villa in Eastern Europe?

Hi,
My boyfriend and I have to attend a wedding in Poland this September. I had thought that it would be nice to move our Summer vacation to that month, and perhaps rent a house for some time somewehere nice in Czekoslovaquia, Poland Austria or Hungary. I'm totally lost as to where to look. Do you have any useful resources to look at houses to rent for 15 or 20 days? Thank you very much!

If you speak German I would look at www.flohmarkt.at
They have holiday houses and apartment located in Austria

http://www.flohmarkt.at/ferienwohnung/
this is the one for apartments

good luck

I have found nice rentals through www.homelidays.com before. They have rentals from all over the world and maybe you have luck and find something there.
