Take a look at Villas Plus web site they have lots of nice villas which are all geared up for famillies with extras like playstations and cd and dvd players etc.
There is also owners direct which lets you book direct with the owners , then sort your flights out yourself. With Villas Plus you can choose whether you want to sort your own flights out or have them included.

Hi, I will second the Villplus recomendation. The prices seem a bit scary at first but if you book your own flights, insurance and car if required you can bring it right down. They also have pool table and ping pong table in all their villas which teamed up with a bottle of wine and a bbq is a fun family tornament night, (or is that just me!). The reps with villaplus are fantastic aswell. You also have sky tv (not all the channels but enough to keep kids amused while grown ups are getting ready), ps2 and dvd player. If you book with them you wont be disapointed.
