It was realy nice to meet Sofia. She presented us her lovely apartment in the heart of Lisbon and was very kind.
We didn't spend too much time in the apartment, because we mainly wanted to see the city. But the time we spent there was great. We felt very comfortable in the flat and it's located perfectly. The most important things/sights are easily reachable by foot and still it's located in a very quiet street (especially no noise at night).
The apartment itself is very modern and stylish and spacious, it provides everything one needs for a city trip.
I would totally recommend Sofia's apartment.
