The flat is ideally situated right the in the center if Lisbon. We weren't sure if, as a result, it would be noisy be the noise insulation of the windows is great and we didn't hear the street much at all. The doors (both for the building and the apartment) are opened with codes which is super convenient since it means you don't have to carry keys around (even if they are made available). Liliana and Sofia were a pleasure to talk to and very responsive. Would very much recommend!
