I came to Lisbon for 4 days with my parents. A week before our check-in Joana sent us a very precise and detailed description of the apartment and the neighborhood.
When we arrived to Lisbon, the taxi driver unfortunately did not know how to bring us to the building and we had to climb the stairs to reach it. However, later we learned that you can take the Ascensor da Bica (free with the Lisboa Card) on Rua San Paolo up to Largo Calhariz , and then go down to Travessa do Cabral, in order to avoid the stairs.
The apartment is really clean, it has all the necessary equipments, you can cook everything you want in the kitchen.
Speaking about the location: besides the fact, that there are a lot of crowded bars and restaurants around the building, it is very quiet inside the apartment. It is close to Cais Do Sodre and Baixa-Chiado stations, to the stop of the famous 28E tram, to Praca do Comercio and Time Out Market.
Overall, the apartment is perfect for people who want to visit Lisbon for a few days, and be close to all the places of interest in the old town, but at the same time enjoy the comfort of a modern and cozy accomodation.
