Kołobrzeskie Towarzystwo Tenisowe
I found it interesting. The club has been renovated this year and a club-house is planned (or has been already built lately).
Kołobrzeg is very nice in addition, I know this city for a long time because I was spending my summer holidays in a city beside when I was younger.
It could be perfect for a little ITF event ($10,000 or even $25,000) during the summer.
