I found the apartment to be the perfect location and super charming. those 5 flights of stairs are quite steep but once you get to the apartment and get to look out over the rooftops to the Tagus river from the tiny balcony and enjoy the sunshine through the skylights you will appreciate the climb. And speaking of steep climbs, the walk down the Ascensor de Bica path leads you right to the Mercado da Ribeira (Time Out Market) or the short walk up into the Bairro Alto. Even the Rossio train station for your day trip to Sintra is only a 12 minute walk. Several of the rooms are kind of small and clearly carved out of the space available but the kitchen had everything we needed, the bedrooms were fine and the living room had plenty of space for our family of 3 to spread out. We were there in December so we appreciated the heaters in the bedroom (including moving the portable one to the living room when we were hanging out there one evening).
