I am a tour guide in Lisbon area: Lisbon, Cascais, Sintra.Also can do tours in Oporto and in other Portugal areas but my main speciality is Lisbon.I do private escorted  tours for small groups of people: 1 to 8 persons.Also can do for bigger groups but I like to get to know people well and make nice friendships out of my clients. See here my profile in Tripadvisor, with some of my client's recomendations.
