Once you are here you are likely to choose a house in Spain.
In 2011, my wife and I also looked for a suitable accomodation and drove from the border of France to Cartagena, visiting the Balearic Islands. We saw a lot of simply magical places along the coast, but finally we stopped and chose Torrevieja.
It seemed to us that it satisfied all our needs as a family living in Spain. Besides the sea and the sun (sunshine 300 days), we liked that there is a fabulous infrastructure and abundance of amenities. The area has international schools, Alicante University, Hospitals and medical institutions, sports and shopping centers, it is close to the airport and other pretty large cities (Alicante, Elche, Murcia).
