We had a very nice stay at Sofia's place. The apartment looks exactly like in the pictures, it's spacious, modern and sunny. It's quite convenient to get to the centre of Lisbon with the underground. Sofia was helpful when the internet was down and she was easily reachable. The only problem we had was the fact that the apartment is right beneath a flight path where plans pass quite low every 10 minutes during the day and it might affect your sleep if you are sensitive to loud noise. Overall we enjoyed our stay, the location is convenient for getting to the airport and other places (if you need to catch a bus to the South of Portugal).
