Transfer itself was excellent and very comfortable. Driver was waiting at International Arrivals. He was courteous, friendly and helpful, and gave us lots of useful information as we drove into the city. However, beforehand we were unable to comply with the request to confirm our arrival details as the telephone number of the supplying company remained unanswered at every attempt. Viator were quick in responding to my e-mails asking what was going on, but that hiccup did cast a slight shadow over our first experience with Viator. In the end, however, they delivered the goods in a very satisfactory manner.
Driver sent text to phone asking for terminal and entrance number and picked us up at door. He was friendly and we were pleased.
