I’m in complete agreement...it was arranged and scripted to be a ‘mistake’, but the place was likely in terrible condition and could not be made livable. I’ve been to the nicer places that have been kept up in Germany, Netherlands and Italy...with tons of money put into a decade-long restoration. If you got lots of government money....you can wait a decade for full restoration. In this case? Erase your issue and start fresh.
I know. Could you even find anyone in France who knows how to fix “winding marble staircases”? And even if you could could even a Russian mafia boss afford the French marble staircase workers union rates?
