Apart from the garden, its horrible. I used to live nearby in Balham many years ago, and almost bought a gorgeous Victorian Terrace in Streatham for 220k, but didn't as transport links were rubbish. If that ugly flat is worth 750k I dread to think what Victorian terraces are going for now.
I also have fond memories of the Elvis impersonator, not so much the kerb crawling and prostitutes, although this was 20 years ago.
