That sounds familiar but I cant think exactly where it is other than quite central.
Hanioti is very low Key and is a summer resort, everyone who stays and works there in the summer goes to the city of Thessalonika to live in the winter.
There isnt any nightclubs as such so there is no rowdy single sex groups or anything like that.
It is mainly families or couples.
There are plenty of restaurants and bars to have a meal and drink.
Plenty of shops and mini supermarkets which sell everything from shampoo to nappies.
There is a popular place called the Hot Goblin too which does huge jacket potatoes with whatever filling, they all do sarnies/baguettes for flights and english brekkie if thats what you want.
We tend to visit The tropicana and the Gusto Italian Restaurant in the square for the best evening meal such as stuffed peppers/tomatoes etc or Italian food. Stones bistro is good for breakfast as is the Amethystost too. There are plenty of restaurants we haven't even visited them all yet and we have been three times!
Seeing as you are called madmum I take it you are taking the kids?
If so there is a few parks , a place called fairtopia with trampolines/bouncy castles etc for the little ones and also a mini 4x4 circuit.
Let us know if you need to know anything else.
