If you are going on a holiday soon then contact some local agents when you are there as at least you can have a look around adn see the area and quality etc. Also look in the Sur in english or Euro weekly or local free paper as some will be advertised there.
Most owners list their properties with agents as they live in the uk or ireland etc and cant sort viewings etc. Dont give any deposits or anything at this stage but suss out what is there.
As soon as you see an agent they will be able to show you property the same day!
