I´d agree, as soon as the terrace lights are fitted and there are signs of occupation, ours were hit. Don´t be complacent and fit shutter locks and window locks as a minimum, check your insurance too, as some policies are not valid of you have no protection at all, as some of our owners found out to their cost.
Don´t deny it is a beautiful place, but use your common sense please!
I run a rental company here in Puerto de Mazarrón, and we found the police to be very helpful when a couple of our owner´s villas were burgled, however I do speak spanish and I am sure that that has a lot to do with it. The Guardia came out, took Scene of crime photos, took away evidence and fingerprinted the windows and frames where the thieves had gained access.
Always worth reporting, as the more people report the break-ins, the more the police are aware of the scale of the problem and will begin to take it seriously.. please do report it!
Try owners away, they do furniture, lighting and tailor made packs for most things.
They advertise in the chronicle, ot google the name for the website.
