I am there from 21st Jan to 4th Feb, so cannot meet with you. We know the area very well having had a a house in Manilva for over 4 years.
If you intend to hire a car look at brunoscar on the internet we have used them for 3 years until we bought a car. I still use them for parking at the airport for my Spanish car now. Hire is best from about 150 euros pe week, taxi is about 80-100 euros each way depending on day/evening. Airport Bus is cheapest Malaga Airport to Marbella is about 5 euros each way and then taxi or local bus, but slow. Airport Bus more frequent in Summer time.
If you want send me an email to manilvajl@hotmail.com and give me your landline number, I can call you as I get free UK and Spanish calls from the UK. Or if you email me I will send my number and you can call me.
