The apartment is newly renovated and the view over Lisbon is just amazing. The location of the flat is perfect, tram is right next to the street, but it is still quiet as it's located in a smaller side street. Also the flat is equipped with everything you need.
Martin is a great host and had many recommendations what we should see and whats the best way to get there.
In summary: Definitely would stay there again, 100% recommended!!
