Thank you everyone who posted on this. We used Malco - they were very efficient, although very expensive and on our return, we found that they had taken the £200 deposit from our card on the day we arrived and it can now take up to 25 days to be returned to us. When we arrived at the airport to come home last Sunday, we found that Goldcar had now opened up in the airport so at least there are now two options.
The airport itself is beautiful - plenty of seating, polite staff - even going through security was a pleasurable experience. Unfortunately, we were diverted to Valencia for our return flight due to "fog" - the airport is built quite high up in the mountains and we wonder if this may be a recurring problem in the months to come. Ryanair handled the situation pretty efficiently - they organised buses to get us to Valencia airport and it ended up with us being delayed for around 3 hours - it could have been so much worse. I would love to use this airport again in the future, but will be keeping a watchful eye on whether other flights are affected by adverse weather.
