We stayed a few mins down the road in Polychrono and visited Hanioti a few times, it's a nice friendly place.
Whilst in Halkidiki we went on a 'greek' night up in mountains which is always good for a laugh. We spent one day doing a cycling tour of the peninsular which was a great way to see local villages and meet people. The guide, who was really informative, collected us and another couple and dropped us off, the bikes were a good quality and helmets were provided. We also went diving, although the visibility wasn't that good and there wasn't as much to see as other places we've been to.
Hope that helps.
