We had a really good time with Carl and Peter. We came to Barcelona all the way from Jakarta, Indonesia. We took the one day three countries (France, Spain, Andorra) trip. They were very friendly, knowledgeable, kind, and very thoughtful. One of our family member is in a wheelchair and they were very very accommodating. It was more than a trip for sure, the conversation during the trip was very fruitful too. We are so glad our path crossed. Highly recommended!
