We had very pleasant days in Lissabon. The communication with Fernando & Stefania was fine and we had no problems at all. The house is o.k. for four persons: we were two couples. It's nice to see another part of Lissabon, from the apartment you walk 15 minutes to the metro and then 20 minutes by metro to the center of the city. You always have a seat in the metro, because it's the first (or last) station of the blue line.
