l have never been to halkidiki before and could do with some info if possible. Has anyone been to the Nostos hotel before and if anyone knows of this place or been there before could you tell me what it's like and the area around there. l know it's near kallithea but do not know much about this place either. Is kallithea lively at night, is there alot of choice between bars with music, is it lively in May as if is when l plan on going. Thanks
