So I wouldn’t describe it as iconic, but frankly I wouldn’t describe anything as iconic, because I’m not 14. I can see why it’s a good fit for her and she clearly loves it, which is great. It’s a pretty good setup but has its flaws - the building looks like could do with a coat of paint and some sprucing up, for example. Instead of saying “the exterior is iconic” perhaps she might say “I love that it has unique features and history behind it”, as opposed to making it sound like it’s a Nash terrace or something…
To be clear I absolutely think it would be sensible for her to say she lives “in the greater London area” or similar, and the same would be true even if she lived in Belgravia. It’s the false persona and hyperbole I object to rather than her being careful (ish) about safety. She portrays herself as tremendously posh and gives an impression of privilege from birth, as others have alluded to here, when that’s not the case, and she has cultivated a brand around west/central London that’s just completely fake.
Oh and on this - it was actually that bathroom that made me sure I had the right place. Another flat in the building has those same tiles, in a bathroom that actually looks infinitely worse than hers. I would hazard a guess that hers is one of the nicer flats in the building.
