I have used Ace twice recently for trips to Heathrow and on both occasions they have been first class. Very polite, punctual, clean car and well driven. My most recent trip was on Friday 1st February when I had to make a dash home from Spain due to a family emergency, so it was very much a last minute booking and of course the weather was dreadful with all the snow. It would have been so easy for them to say no but despite the adverse weather conditions Ace still collected me and got me home safely. Highly recommend this company and will definitely use again and would recommend to others.
