Sofia's place is exactly what I was looking for. I stayed for 2 months in a row here and I would highly recommended it to anyone who is visiting Lisbon. It's located in old and beautiful district of the city, very close to the supermarket and a few minutes away from Praca do Comercio and the river! The apartment itself is very spacious with all the necessaries included. I enjoyed every day of my stay. It might be a little cold in winter, but there are a lot of heaters inside the apartment, so it was not a problem for me. The internet is really fast and I didn't have any problems with it during my stay. Do not hesitate to book it right now :)
