João was extremely helpful and not only welcome us at midnight without additional charge, but also literally saved us when another host let us down. The apartment is equipped to the highest standards & included everything you should need. The location is great and although it's better to take a tram to get to the apartment from metro, you could do it by foot if to use 2 free elevator - one is Elevador do Castelo and the second one is nearby in Pingo Doce supermarket. Then you just should walk 300-400 to the apartment without significant elevation. Here is a detailed video https://www.youtube.com/watch?v=GGe3lzh9Ovg.
