We stayed at Antonio's place on our final night in Lisbon. The location to the airport made it super fast and easy early to catch our flight the next morning (and Uber only cost 4 euros). Antonio is an enthusiastic and generous host. He seems to genuinely enjoy hosting and making sure his guests are comfortable with his apartment and the surrounding area. Communication was clear, and check-in was super flexible.
Our room was cozy and quiet at night. There were nice touches around our room: pitcher with water and glasses, charging cords for various styles of phones, a magnifying mirror (ladies with aging vision will understand the importance of this), etc. Because our bedroom faced the front of the building, there are lots of lights in the parking lot and buildings that shine into the room. On a less warm night, the shutters would easily block all of this out. However, it was a warm night so we had to choose between letting in more light to get some air or keeping the window only partially opened. Fortunately there was a fan in our room, which helped significantly.
I don't know what it would be like to stay at Antonio's apartment for multiple days, but our one day was pleasant enough that I wouldn't hesitate to stay there again in the future.
