We had no trouble finding the apartment after taking the metro from the airport. Dora, a friend of Chiho, was there to let us in and show us around. The apartment is very clean and bright and had everything necessary for our stay, including a well-equipped kitchen. And the view of the river is spectacular! The street got pretty noisy but we were out most of the time and it calmed down at night so wasn't really an issue. The Alfama is an intriguing neighbourhood with so much to see. Lots of hills but that's Lisbon it seems! Would definitely recommend and would love to return.
