Very nice apartment, well decorated and clean. The street is calm and everything's needed can be found in the neighbourhood. Pasteleria, grocery stores, restaurants (like the famous cafe Sao bento). Walking distance from the barrio alto but also from the city centre, my whole family went several times walking down to baixa (ok I only had to drive my old mother there cause it is first up and then down!).
Really nice welcoming, on time, no problem, heating system for winter, everything was perfect!
We had a sunny stay, Lisboa is so beautiful and Portuguese people also really friendly, I recommend this place, of course.
