During a recent trip to Lisbon, Bruno S. guided us on a day trip to Sintra and Cascais. He arrived well in advance of the designated pick-up hour and provided intelligent commentary throughout our journey that was informative without becoming overly academic. Bruno was considerate of our mobility challenges (Sintra is very hilly and we are both in our late 70s); his personality is engaging; and his enthusiasm for his assignment was contagious. While in Cascais, he identified a lovely beachfront location for lunch and we engaged in a lively and energetic exchange of ideas about multiple subjects. We recommend Bruno S. unhesitatingly for anyone interested in exploring Portugal's wonders with a knowledgeable and responsible guide. .
