There are two options available when travelling to northern Cyprus

1) Fly to Larnaca - situated in the South of the country this airport is readily accessible from the UK with direct flights on many airlines.  Taxis can be arranged from the north to come and pick you up, transfer you over the border and deliver you to the villa.  Travel time is approx. 1hr 30 min.

2) Fly to Ercan - the main airport in the North.  The villa is approx. 1 hr from here and car hire can be arranged directly from the airport.  These flights do however stop in Turkey for under an hr so the flying time is longer but overall journey time is much the same as flying to Larnaca.
