An old friend is looking to move back to the UK from abroad. She and her husband have done very well financially and have a budget of £5 million. (I know...)
She grew up in the London area and would like to come back to SW/W London ideally -- but she hasn't lived here for so long she hasn't got a feel for different areas. Her kids will be either at boarding school or uni so no need to worry about school places.
Where would you buy if you were in her very lucky situation? She can't come over to scope things out in person at the moment, for obvious reasons.
