There are apparently 4 cab firms operating in Menorca today.

The easiest, quickest and most recommended is contacting Taxis Menorca via Whatsapp on +34 666 02 88 97. 

Pick up is from Finca Santa Monica and the address is available to them on GPS. They will let you know when to expect your taxi and when going to the airport, they arrive a little early to allow for loading luggage into the Taxi. 

The turning to Santa Monica is now near the Depuradora (treatment plant) on Calle de Talis.
