London neighborhoods/districts

I am arranging accommodations for my parents for a week or so in London and would appreciate advice on any neighborhoods and/or districts that I may want to avoid. They are in their early 70s and so I'd like to keep them out of any sketchy neighborhoods. Thanks in advance!

A lot of "good" London neighbourhoods can have some not so good streets.

If they are not staying in the West End, I suggest places around Sloane Square, Holland Park and South Kensington to name a few. Even Earls Court is quite safe and other places around West London are mostly fine (Gloucester Road, Fulham, Hammersith, etc).

SOme people might hate me for saying so, but I'd steer clear of Brixton, Hackney and Bethnal Green.

If you have any specific places in mind let me know and I'll give you my opinion. I know London well.
