prompt, polite and professional
Our driver was prompt (even early) and was informative and friendly on our drive from London to Stonehenge and then on to Southhampton. He even offered us bottles water at Stonehenge and said we could stay at Stonehenge as long as we wanted. We were given exact pick-up time one week before our transfer. We initially booked months in advance and they followed up once our date approached which was nice.
