Nalan and I will be touring Europe by Interrail this summer (late July/early August). We're planning to do a circular route up through Bulgaria and Romania, across through Vienna and Prague, then maybe taking in Amsterdam and Paris before going down to Italy and winding up in Greece for a more normal, non-train-based holiday. So if you have any tips on places to see and stay, I'd appreciate hearing from you - and of course if you're going to be in that region, we might be able to meet up.
