Eltham? Rough? I think if you grew up in Windsor and schooled at Eton you might think that. Eltham's one of the better areas of London, and I'm not saying that because I live there (I don't).
Crikey, give me a place in Eltham before Lewisham ANY time, Lewisham really is RAF.
In the 90's both areas was rough. Eltham was not really a safe place for a Black person. Lewisham had gang related issues.
Economics, demographics and politics has changed everything. Those issues are not prevalent in those areas any more
Lewisham is not bad place to live house prices on average are 400k>
