• neat = tidy 
  They are synonyms. They are both used to mean 'in order'and 'carefully done or arranged' 
  
  'I like everything to be neat and tidy.' 
  'Keep your room neat and clean.' 
  'He's a neat person= he likes to keep things tidy and in order.' 
  'You should dress neatly when you appear in public.' 
  
  I want to add an idiom that means 'neat and tidy; done or arranged very accurately or carefully'. It is 'just so': 
  'Her hair is always just so.' 
  'He liked polishing the furniture and making everything just so.'
