We used this company earlier in the year with no problems when flying from Liverpool. Booked them again when flying from Leeds.
We arrived at 6.30am, only to be told that they had been closed down by the council and where unable to take any more new cars. Their premises consisted of a portacabin in a portioned off piece of a field - plenty of mud!
We did get our money back with no quibbles and offered complimentary parking next time we used there service, though whether they will still be around is another question!!! We were given the contact numbers of the Director, Jerome O'Malley but when we called his mobile went to voicemail and when we phoned the landline we were told we had just missed him.
At the moment we are giving him the benefit of the doubt but don't hold out much hope!!! We hope to be proved wrong. My advice would be not to use them and pay a bit extra at Sentinel or at the airport itself. I will update this review if anything changes.
