We stayed 4 days in Lissabon (2 adults and one child). The apartment was spacious, well equipped and in a perfect location.
5 minutes walk from Rossio train station, many restaurants, Belem about 20 min by metro, Afama 15 min walk. Really quite street.
The apartment is in an old house and newly renovated.
A 100% recommendation.
The only limitation: 4th floor without lift. Therefore difficult for people with difficulty climbing on stairs.
