The apartment is nice and surprisingly big. I assume it’s about 60-70 sq.m. in total. It is indeed well equipped. The place around is kind of a center of Lisbon street life, but it was really safe and quite (windows overlook the courtyard).
The owners are really very friendly and nice people and respond very fast.
The little problem was with the humidity (I stayed in November), so I advise you to dry your clothes on a clothesline on the balcony on sunny days.
