Diana's apartment was probably considered very stylish in the 1990s.
I hope there isn't a rift, and I really don't believe there is one. The two brothers can't continue to live beside each other, who among us lives next door to a sibling in what is already a pressure tank. It is much easier to spread out to try and achieve some level of privacy surely.
I agree that the number of homes being funded by taxpayers is quite simply appalling. The cost of renovating homes they are only half interested in living in, is disgusting. That said, I read somewhere that after a considerable investment of one (or even two) million in one of the properties, all they had actually done was put in new windows and put on a new roof. The upkeep of these properties seems to be colossal although of course that could be easily reduced by reducing the number of homes they own!
