Everything was great except the heating. We came in early February and the living room would get very cold even with the heat fully on. The main bedrooms were warm but the living room and spare room with twin beds were very cold and made it hard to be comfortable in the space. Extra heating would go a loooong way in the winter months.
Other than that everything was great. Location was awesome, very walkable to beautiful spots in porto. The host was very kind and quick to respond.
The stairs are another potential issue for those with mobility issues. You have to go up four flights to get to the unit and an additional staircase for the bathroom once inside. This wasnt an issue for us but i can see how it would be for others
