Always felt really safe in
Icmeler - well, as safe as anywhere I'd guess. It's like anywhere - some people are good, some people are bad. Want to meet rip-off merchants, try
Marmaris market

Just keep your wallet shut.
To put it really into perspective though, Ibiza is an absolute hotspot for robberies and crime. Not just San An - the family resorts are as bad, some
hotel complexes are targetted again and again by gangs of trained children. Hire a villa - then it's very common for these to be burgled.
Want to get worse - Rhodes isn't very safe for crimes on the person. The resort of Faliraki is particularly unsafe, do not even think of going on the beach there after dark, and it isn't from boozed up brits, it's locals.
Disorientated and over-relaxed tourists will attract the bad guys if they are so inclined, in whichever country they may be. Certainly wouldn't say Turkey was any worse than anywhere else, if anything, you know you get sometimes a "gut feeling" about something - well I feel Icmeler is safer than many resorts, but of course, not totally crime free.
Deffo not something which should ever put anyone off.
