We had a warm welcome when we arrived in Porto by Pedro, who was very communicative and helpful. The appartment is absolutely beautiful, recently renovated, very clean and fully equipped, in a quiet neighborhood, not so far from the center of the town. There is also a metro station in about 4 minutes walk.
I definitely recommend the "Twilight Attic" appartment for accomodation! Next time we will be in Porto it will be on the top of our list!
