First of all: The apartment's large and sunny terrace offers a GORGEOUS view of the douro river and the famous bridge. It's really quite breathtaking, especially at night.
The appartment itself is decorated in a modern, minimalistic but practical style. Everything was very clean. The wooden floors ar beautiful.
The kitchen is fully equipped, there's everything there you may need and then some - we cooked a LOT, and we never missed anything.
The beds are comfortable (not too soft, I like it that way).
The bathrooms are nice and clean.
I think it should be mentioned that there are no doors inside the apartment except for the bathroom doors. It's basically all one big open space. The two floors are connected by a narrow stairwell that offers some separation. The double bed is on the lower floor and the four single beds are on the upper floor.
As mentioned before, there is a stairway inside the apartment and the apartment itself is on the third floor with no elevator, so be prepared to climb some stairs every day.
Anne was very friendly. She welcomed us warmly and made sure that everything was fine throughout the stay. Because we were staying longer that a week she even changed our towels and claened the apartment after a couple of days.
I wholeheartedly recommend this place!
