We had a great stay in this apartment. Small but mighty. Has everything you need and great location too.
Only thing to reiterate is that the stairs from the main door to the apartments are VERY steep, near vertical. Also as other reviews have pointed out, walls, ceilings and floors are extremely thin. You can hear everything that happens above and below you, and they can hear you so be considerate of your neighbours as you would wish too. We didn’t experience any significant issues with this but light sleepers might want ear plugs.
Thanks for letting us stay and we will definitely be staying here again if we visit Lisbon again soon.
