We (4 persons with 8 luggage) booked three transfer trips with Twelve Company in May 2016 via their online website (after we researched thru Tripadvisor's website for positive opinions) for the needed transfers from Heathrow Airport to Hotel, Hotel to Southampton Cruise terminal, and from Southampton Cruise terminal to Heathrow Airport for our recent 14-night Mediterranean cruise. The provided transfer trips were all on time with excellent drivers and vehicle conditions. Costs for the three trips were low and comparable to other transfer providers in London area. Their online and email services were excellent for booking and communicating messages. The agents were excellent and promptly responded to our emails and chats. Thanks for providing excellent services. We will use your transfer services again for our future visits. H. Phan
