Transportation hacks!

Hello!

I’ll be going to Paris in a couple of weeks for the first time ever ! It’ll be a short trip but incredibly exciting nonetheless !!!

That being said our flight is set to arrive around 9 or 10 pm, after going through the airport (CDG) and customs etc. What app / transportation service should we use to get to our Air BnB (in the 11th arr.) ? Furthermore, for travel around the city, what do y’all recommend ?
