Both the pick up from Madrid airport and the driver were excellent. However, the return pick up, from JC Rooms Santo Domingo on 24th September involved a driver who wouldn't help with the suitcases, who parked in a location where we had to squeeze past scaffolding to put our luggage under the bus and who opened and closed the doors of the bus while people were trying to squeeze past. Very dangerous. In addition, as soon as we started boarding the bus, we alerted him to a previous passenger having vomited on the bus which had not been cleaned up. We were fortunate that they were two extra seats and we only needed to use the other 50 seats. I am disgusted and after many years of using Zip Transfers, I will use another company in the future - that driver's attitude was rude, uncaring and unacceptable. I must stress however that the other driver who collected us from the airport on 20th September was exemplary in every way.
