We just furnished our in Feb.
Got lighting done by Martin at Condado Services - Just easier i thought and for price a good job. I got extra spots fitted in a couple of room.
Air Con I used Apollo Air as well after much searching. Caroline who you will email s great and they came and fitted the day we arrived.
Electricals I used Euronics. Again convenient, they deliverd at a set time and any problems wit appliances for first 2 years you can go back to them. I got washer, fridge freezer microwave and 4 TV's.
Most of our furniture we ordered throug ikea via easyflatpax. they charged 15% for doing the shopping for you and delivering but delivered again at the time they said they would. Just spent 3 days building. You can do a list on-line at IKEA Murcia and just send it to the lasy here. They then check whats in stock day before and you can give alternatives just in case.
We were out for 4 days and did it all just about and did not have much time to shop around etc. I would not get the furniture packs as we got one bed from a company and the mattress was awful compared to the IKEA ones.
Hope this helps - good luck.
