I've been in Monaco only once, when my student budget advised to have a look and move quickly to a more affordable place.
Unhappily, a tremendous fire in Côte d'Azur that killed more than 40 people, forced to a nervous and long delay, so, the quick look was even quicker and at night.
I'm planning a new visit. It almost happened in 2017 when I tried to participate in the European Masters Games, in Nice, but the plans failed.
It is in the agenda...
