The apartment is really nice and very clean, exactly as in the photos, it is also well equipped. We have not met Sofia, but her boyfriend, who was waiting for us in the flat quite late in the evening. He was super friendly and gave also some tips for Lisbon. Sofia was a gerät help even before our stay in Lisbon giving tips how to get from Porto to Lisbon and so on. The apartment is not central but you can reach subway in 10 15 min and easily get to main sights. I would really recommend it to the future guests :)
