The meeting point is specified in the emails and texts that you received from us (confirmation email right after payment and reminder the day before your departure).
Usually, it is the drop-off point of the airport/train station, unless there are exceptional conditions (works, for example). In any case, the location will be specified to you in our emails.
If you cannot find the meeting point, contact your valet who will then easily guide you. For a pick-up request at a specific location (hotel near a train station or an airport for example), please send your request by email to firstname.lastname@example.org.
