The apartment is perfect for adults. We visited with a 11 month old baby and we can say Its less adapted for young children. It’s normal to expect stairs in Lisbon but they are very narrow and steep so it can be difficult to bring many luggages to the apartment especially with baby equipment. The location is great, close to the metro, time out market and the Bairro Alto. It was noisy only one night, otherwise it was very quiet. It would be nice to have blinds in both bedrooms. Nice view from the windows. One of the restaurants down the street has take out, if you have or want to stay in for dinner.
