We liked our stay in Portugal.
The apartment was big enough for 5 of us, clean. Don't know if it is a season problem (November), but it was very damp in the apartment (strong smell of mold), that was the biggest issue that we had. Dehumidifier was in the apartment and we let it run all day and all night (that helped a little). The position was good, getting to the center/turist attraction was easy, good connection to buses and metro.
I would ask if the problem with the dampness and the moldy smell is solved before renting the apartment again.
