C’est trop!!
Zéro
Terrible not thought out, integrated or real -time
We found it made us get out of the metro into the train system, then back into the metro from the airport.
It’s like getting directions from someone who is not thinking about timing or efficiency just step 123 on a map old school.
Use the app as a Map but make your own decisions re timing and routes. And stay in the Metro system as opposed to the train system where you can.
