"Everything was great. Our driver was very responsive and did such a great job. He was chatty and great to talk with. He delivered us to the address quickly and safely. He deserved the tip I gave him for his quick response and through completion of the job I hired him to do. I wish I could request him every time I come to London."
"Excellent driver. On time, helpful, polite and courteous..
Just a small suggestion: Perhaps a reminder mail 3 days before the ride, so all details are easily to hand?. I had to go digging back in my InBox to remember the details!"
