Flights to three airports give easy access to the area: Malaga, Seville and Jerez: From any of these the drive to the villa should be one and a half hours (possibly less from Jerez), and the roads are excellent.
Gibraltar is also an option to fly to with BA, but the journey in Spain would be longer.

Check websites for schedule or charter flights, e.g. Opodo, Expedia, E-bookers, Easyjet, Ryanair, or national airlines,etc. Prices vary but are generally competitive if booked early.

Malaga is the busiest and offers the widest choice of airlines flying there from many UK airports, including several Easyjet routes.

Seville has British Airways and Iberia (combined service) arriving daily except Sundays (seasonally this may vary) from Heathrow or Gatwick, plus other airlines seasonally my operate routes there from the UK.

Jerez is served by RyanAir from Stansted. It is a quiet airport, which is great for convenience.

Car hire is essential. We can recommend Travel Autos who are agents for Crown Car Hire in Spain. You can book with them in the UK, and whilst we cannot take responsibility for your booking we have always found them 100% reliable, and in our experience their prices have proved more competitive than if you book direct with Crown or others in Spain.
They serve all the above airports.*

* At Gibraltar the car hire is not within the airport complex. You need to walk with luggage approx. 200 metres – i.e. across the border into Spain!
