Great home base for a stay in Lisbon - my partner and I stayed for 1 month and worked remotely with no issues. High ceilings, lots of windows, a spacious floorplan, and great river views make the place feel huge! Excellent location right next to Lisbon's histroic Alfama neighboorhood, walkable to many sights and the city center. Fast wifi.
One clarifying note is that the AC is only in the master bedroom and it did get a little hot in other parts of the apartment, though we did stay for the month of August, when the weather is warmest. Overall would absolutely recommend to anyone visiting Lisbon!
