We - my 17-y old daughter and I - made a city-trip to Lisboa and stayed at Sérgio's house in Alfama. It's been a great time, Sérgio came at the airport to pick us up - although he was very tired - and, when we arrived at the flat, everything was ready, even de pasteis de bata were waiting for us ! The neighborhood was perfect, with everything (public transportation, shops, places to see, docks, restaurants, ....) on walking distance, and the house is very quiet. Thanks Sérgio for being our host, and ... hope to come again soon !
