What surface is the tournament being played on?

With it being in Greece I would have thought clay but I am not sure, can anyone say?

See the fact sheet thread above. It's Deco Turf II (same as US Open, I believe).

yes i believe it was originally supposed to be clay except there was a late switch to it being hardcourt

Well, it makes sense seeing as it's in the middle of the hardcourt season...
