I arrange a surprise tour for my wife and friends. Carla was wonderful to have as a guide as she was knowledgeable and able to answer all our questions regarding history to today's modern Lisbon. She drove her car safely and she also found a fantastic vegetarian restaurant for us for lunch. Carla was flexible and adapted the trip to our wishes. We only have superlatives about Carla; flexible, knowledgeable, service oriented, nice and talent. Well spent money and the whole group was very happy afterwards .
