Carlos was a very friendly host and responded quickly to questions. We didn't meet all that often because we were out exploring most of the time. The apartment was roomy and comfortable. The neighbourhood (Alfama) is one of the oldest neighbourhoods of Lissabon which we liked very much. There's lots of beautiful spots within walking distance of the apartment, and there's a great lookout point at the castle of st.George. You can easily walk down to the Baixa and even Chiado areas, and once you're tired of walking you can take the famous little yellow tram. We only used the subway for the longer distances. All in all this place is easy to recommend!
