Carla is a nice and attentive host . The check in process was smooth and welcoming. Flat is 10-15 minute walk from the nearest metro depends on how fast you walk. Once you are at the metro, within 20 minutes on the metro you will be in the centre. I highly recommend the little family restaurant around the corner which has really excellent grilled fish for lunch that was very affordable. For breakfast the cafe at the corner near the Loule near the Marque de Pombal metro has good options. Carla's place is nice and cool despite the hot weather. The city suite we stayed was very nice and comfortable. A good value en-suite room not too far from the city.
