Our stay unfortunately came during a heatwave in Lisbon, so it was very hot. There were only two fans also, one vintage fan did not oscillate and seemed rather ineffective, while the fan in the bedroom did oscillate but was too small to really be effective. A tower fan would have been preferred in both locations. The 3rd floor of this unit made the stay there quite uncomfortable, especially for sleeping. Opening the windows did provide a cross breeze at times, but because they had no screens on them they could not be left open when we left the unit, so it was always hot and stifling when we returned.
Several floorboards in the unit were loose or would pop as we walked on them, and in between the boards they would have gaps that would catch and seemed dangerous. There was also nowhere to hang towels after showering. The rack that held the towels was not ideal, but there was an empty wall that had nothing on it that could easily have had hooks or rods to hang towels to dry. The floor also seems to have not been cleaned as walking around on it our white socks turned brown, as did our bare feet.
All that aside, the location is very convenient in the city, it's very close to many shops and restaurants as well as metro stations or trolleys. It's walkable to many different neighborhoods though we didn't get much time to explore everything. Be prepared to walk up steep hills if you stay here or a multitude of steps. You will definitely get an exercise coming back and forth, so make sure you don't forget anything when you leave.
Also, the view out of the unit is quite amazing for sure.
