We were 4 people and stayed for 4 nights. The appartment is well situated close to the city center and Douro river. You can easily visit by foot or take public transports. There are 3 large bedrooms and also a tiny one that you access from the kitchen. If you have light sleep don’t forget ear plugs as the 3 large bedrooms have windows on the avenue, it is quite noisy.
We enjoyed our stay at Olga’s place, the appartment is perfect for group of people or a family. The view from the living room is really nice. Contact with Olga were very fluid. As we came in winter time heaters in each room where really enjoyable.
