As regards the power supply you are best to get a comment from someone who has got an apartment of the same size, it definately costs more to have more power available and i very much doubt you will need the full 9.2. You should factor in if you are going to get additional aircon etc.......(you may have it to all rooms already). Maria at customer services is the best person to speak to.
We completed a few weeks ago and have just finished the wiring of lights etc. There is no-one there to do it for you but are lots of adverts for local electricians in the free press if you don't fancy it yourself. There are loads of lighting shops around in Vera and Garrucha ranging upward from E30 for modern or "spanish" fittings depending upon your taste - there is also an Ikea in Murcia.
The furniture should be there, albiet wrapped up when you get there - all the standard stuff - beds, mattresses and covers, dining room tables and chairs, sofa and coffee table - but no outdoor furniture, knives and forks, pots and pans etc. The curtains/blinds are up!!
Hope this helps..............
