Sofia's place is very spacious, with high ceilings and a well designed interior. While we weren't personally greeted by Sofia, she was always easy to contact, hospitable and kind. The apartment is located in a calm neighborhood from where the metro to the centre, the viewpoint of Graça and a supermarket can be reached with relative ease. That being said, do not expect a very clean city or direct neighborhood. Trash on the streets seems to be something that can occur in Lisbon but for us it doesn't take away from the charm of the city.
