A Barcelona chauffeur service is private transport contracted in advance at a fixed price and carried out by a VTC operator authorised under Spain's national transport law (Ley 16/1987, the LOTT), which files each trip in the Ministry of Transport's electronic VTC register before it starts and works within Catalonia's Decreto-ley 4/2019. In Spain a chauffeur car is a VTC: it can only move with a contract already in place, which is exactly how a RYDES booking works. The class of car, the chauffeur and the euro price are fixed beforehand, whether you need a Barcelona airport transfer, an hourly car service in Barcelona or a black car to a Diagonal boardroom.
What changes is who carries the risk. A metered taxi from El Prat adds a €4.60 airport supplement and runs on the clock when the Ronda Litoral jams; an app ride must, under Catalan rules, be booked at least 15 minutes ahead and cannot show you cars before you commit. A reserved Barcelona car service booking sets one figure before the day, and that figure already holds the 10 percent VAT (IVA), any C-32 or Vallvidrera tolls on the route and the car park charge for collecting you at the terminal. The honest comparison, euro by euro, sits on the Barcelona taxi alternative page.
The same reservation reaches well past the city limits. Cruise terminal transfers from the airport to the Moll Adossat, El Prat to Fira Gran Via for trade-fair week, Girona airport to Barcelona for low-cost arrivals, and El Prat to Sitges or El Prat to Andorra when the trip begins at the gate and ends somewhere else. Regular travellers can run it all through a corporate travel account in Barcelona.
