I had a terrific stay at Sergio's apartment. The location is the best - a block from the Se de Lisoba (the Lisbon Cathedral) - short walk to the main square by the water and the Metro station, right in the heart of the Alfama, 15 minute walk to Rossio Train Station. And though in the heart of the city, the apartment was very quiet at night, so easy to sleep. Sergio was very kind, picked me up at the bus station and took me on a short driving tour of Lisbon, then even shared his lunch with me. He was only there one of the nights I stayed, but kept in touch by text throughout my stay to make sure I had everything I needed. I would definitely stay here if I were to visit Lisbon again. Highly recommended!
