There are 6 of us flying into Madrid and staying in Plaza Mayor. How do you recommend we travel to our appartmemt from the airport? Gracias 😊

There were flat rate taxis when I was there is 2014. With 6 people, a shuttle company might be cheaper than 2 taxis. I'm searching for the company I hired who didn't show up because they had the wrong day! There are quite a few shuttle services--just remind them if your flight is an overnight one! Can anyone help?

As mentioned you would need two taxis, 30 euros each, or if you can, find a shuttle company with a van
or
You can take a bus to Atocha train station, metro from there to Sol, and walk a bit to Plaza Mayor.

Thanks all. Can you just pick up a taxi or shuttle at the airport or do you have to book?

don’ know about shuttle,
there are numerous taxis at the airport and all over Madrid..(.never had a problem getting one).

Taxis will be waiting at the taxi stand as you leave the arrivals terminal. As noted, the fee is a flat fare of 30€/taxi. You will require two taxis. A shuttle has to be reserved in advance. With six people, the charge from Aero City should be around 40€ for up to 6 passengers.

I've used Aero City, they did a good job.
