Every bathroom is equipped with a hairdryer, so there is no need to pack one.  It seems as though most curling irons etc do not work well on a current adapter, so we usually advise guests to leave them at home.  Any electrical appliance that you bring that does not support 220-240 volt current can only be plugged in through a current converter.  Most cameras, IPods and cell phones will support 110-240 volt, so you should be able to charge them at the villa. (You can usually find this information on the electrical cord of the appliance). We have standard European plugs at the villa's and USB plugs in the bedrooms so keep this in mind.  You might need an adapter.
