Pedro and Sergio's apartment is possibly the best you can get. On the day of arrival we were greeted by Pedro at the apartment and he was so helpful to help us with our baggage up the stairs. Thoughtful touches included having the air conditioning on the moment we stepped in (essential in the summer heat!), pastries as a snack and even some wine. Pedro was really welcoming and also gave us a rundown of Lisbon hot spots and recommendations. The apartment alone is spacious, clean and perfectly comfortable - we enjoyed our stay very much that we were sad to leave! True to word, the apartment is just a touch away from the famous tram 28 line and perfectly centrally located in the old town - we pretty much walked everywhere. No doubt a highly recommended stay, and I'd love to myself if I visit Lisbon again!
