This distinctive blue mansion is now a beautifully restored hotel and apart from staying here the only way to see it is on a guided tour. These are free and run in English twice a day. We were brought round by a very entertaining (and quite stern!) lady who really brought the history of the building to life. Don’t let the fact that you have to wait for a tour put you off; the building would not have been as much fun without the guide.If you know the French movie Indochine, it may look familiar as it was filmed here.
