You're quite a way out at Sani for looking for work,you really need to get further down the peninsula to Polichrono,Hanioti,Pefkohori area if you want a good chance of finding a summer job which will take time out of your holiday as you'll need to have a think about what sort of work you want to do & then it's a case of just asking around bars,shops,restaurants etc,also bear in mind that not a lot of jobs offer accom now either so it'll be a case of finding a job then trawling round looking for a room,there's plenty for rent & they'll usually do you a good deal if you're there for the season..You might get a few offers through this site but to be honest i'd try & get another holiday later in the year in one of the other resorts & sort something out for next year!Good luck & if you need any more advice or help then send me a private message or something,i have 6yrs experience of working in Halkidiki!
