1) It's London.
2) London is a drab, alienating, vacuous dump.
3) People who pay £3M for *a flat* in that place, golly, that's worse than a stretch of jailtime.
A trifle harsh!
Truth is truth; have you been there? I used to go weekly, my opinion remains.
Many more years ago than I like to contemplate during a "working holiday".
I did notice that not many people where I was living in Southampton had any great enthusiasm for London.
Of course, I went & saw all the well known sights, but really, unless you were of the theatre going milieu, it did pall after a while.
I remember one weekend driving up to London to buy some "Colonel Sander's Kentucky fried Chicken".( KFC to all you "Yutes")
Back in the 1970's there were, to my knowledge, two such outlets in the UK, compared to 6 or more in Perth WA.
The KFC was cold, & served with chips, which they didn't use in Oz at that time, & I was astounded at how quiet central London was.
You pretty much could have "fired a cannon down the Strand without hitting anybody."
That said, although London does seem to suffer from a "cultural cringe", comparing itself with Paris, my impression is it is every bit as attractive.
Of the limited number of European capitals I've seen, though, only Rome seems to live up to the hype.
