The apartment was exactly as described. It was very spacious, clean and fully equipped. Especially we loved the pampering, spacious shower.
Mafalda was there to warmly greet us and give us tips and suggestions about getting around and seeing sights, especially local tips that would be hard to come by in hotels etc. She also saw us off at the end of our stay and helped us getting a taxi.
The neighborhood is very quiet and quite a hike from the other neighborhoods, but then again any walk from A to B in Lisboa entails a hike up/down a hill...:-) One advantage is that it is equally distanced from each of the neighborhoods of interest (Alfama, Barrio Alto, Chiado, etc.) whereas staying in any of these neighborhoods would mean a longer walk to the other neighborhoods.
Overall an excellent experience which definitely enriched our stay in Lisboa. Thank you Mafalda!
