I use Zip transfers on almost every trip I take and have always been more than happy with the service especially the drivers who are usually very pleasant and polite and I have never had a complaint, but we were not a bit happy with the driver of our last trip from marina suites to las palmas airport. the driver was rude, never spoke one word to us, just just nodded when we asked him questions, he broke the speed limit on numerous occasions to the extent my daughter and wife were actually terrified for their safety. While I understand he has probably a time schedule to keep to, this in my opinion is not acceptable and putting passengers safety at risk through speed is definitely a no no for us.
