The location was perfect for our family. While the tower stays open until 11pm, the streets aren’t too loud at night. We preferred being on top of the hill as opposed to the busier city center as it only a quick walk to access the center.
The biggest drawback was the layout of the apartment. The narrow hallway that connects the sitting area to the bedrooms did not allow for the movement of air. It was extremely hot in Porto while we were there. The apartment was very hot our first night, which made sleeping difficult. I think if the weather had been better, we would had a perfect stay. It definitely has a cramped bed/bath area, but the sitting area is great!
Again, the location was great!
