Recommendations for a car service that can be booked in advance for transport to CDG

For transportation to the airport, I book with a G7 Taxi. They have been very reliable. Uber has been a complete total disaster, and I’ve not had great success with car services.

The car services in Paris have lots of horror stories. So I just go with G7. I downloaded the app and do everything on the app works great and you get the flat rate versus “we can charge you €200 because we’re a car service” They do add I think seven euros for the reservation but well worth it my opinion

Call Taxi G7 or download the app and book a taxi a day or two before the travel date. In addition to the flat rate fare to the airport, you will be charged a 7€ dispatch fee.
Edit: If you still want a car service. i suggest/recommend Shuttle Inter. The cost is 75€ for up to three passengers from any location in Paris.

Another vote for G7. Definitely book at least one day, and preferably two days ahead. They get busy. And be ready and on the curb at the appointed time. In my experience, they're usually 5 minutes early.

You specifically asked for a car service and so I will give you the one we use. You've had lots of recommendations for taxis and G7. I've used them both. At some point, I just had one too many bad cab drivers - whether it be Uber, G7, or the taxi line - and I generally pay more for a specific ride service. Many people would make a different choice - but this is what we do.

I like them: https://www.bt-transfer.com/index.php?lang=en

It's 90 Euros.

I've used G7 to the airport at least 20 times and never had one not arrive about 5 minutes ahead regardless of the time of day -- they also clarify how many in the ride so they can dispatch a van cab if necessary. And they have depth i.e. we once had a private ride booked in another city and the driver was ill and they didn't have a backup to send.

I haven't used it in France, but in at least 3 other countries I have used https://daytrip.com/ . They are a little pricey but so far very reliable with nice cars.

OP did not state what the pick up point for the travel to CDG is.

Everyone seems to have assumed its from somewhere in Paris. Probably not an unreasonable assumption, but not grounded in actual fact.

Ask your hotel or landlord for recommendations. It is unlikely you are the 1st to need to get to CDG from there.

Thanks so very much for all the helpful recommendations. I really appreciate everyone's help.
