There was no sign stating that the parking place near the Asklepeion is guarded and/or paid. On recovering the car I had an argument with a man who cane running to me claiming I owned him 3 TL for parking. I asked him why he came now, after I had parked, said their was no sign of paying for parking and asked for a legitimation: he showed something like a book with receipts from the community. I was not convinced and several men in the café started to laugh as he turned to them for help. In the end he became angry and ordered me to go without paying.
Unique Suggestions: Check before you park: there is plenty of space.
