I'm a 29 y.o. guy from Belgium. I'll have ~1 week of holidays in September. None of my friends will be able to join.
Any suggestions of possible places to go to and things to do by myself? Seaside would be nice (Italy, Spain, Greece?). Or some interesting acitvities (wine courses, kite-surfing lessons, language classes)? I've already been in most European capitals, so a simple weekend trip is not considered.
If you have done something similar, please let me know! Thank you!
