I lived in Brunswick the regency area of central Hove for six years but returned to London because of the terrible drug problems the place has. Many coastal towns in kent and Sussex have serious issues with county line dealers down from London openly selling their poisons to mainly street sleepers/homeless. It's heart breaking to see and it's rife. The police and council moved the problem elsewhere when they eventually done a purge on central Brighton where most of the addicts congregated and also begged from. It's a doddle for dealers who see these places as sleepy, backwards and much less a risk to them compared to trying to compete, avoid arrest and rival gang members in a very competitive and cut throat market that is London.
Most of the regency stock looks beautiful, has character and spacious rooms but are terribly expensive to keep warm during the winter because the heat escapes from everywhere. The walls get soaked too once the heat escapes. The buildings are old, no double glazing and no insulation.
Aldrington is nice, clean and peaceful as is parts of Shoreham. Rottingdean, and Saltdean.
