The apartment itself is lovely, exactly as in the pictures and in a great location (checkout O Caseirinho nearby for a delicious unpretentious lunch) from where you can walk or take the tram around the city.
The house is divided into four apartments and our stay was unfortunately marred by the guests above who kept us awake all night. I think we were unlucky but perhaps think about bringing earplugs (or staying out all night with the revellers if that's your thing).
Anyway, the staff at the welcome centre were efficient, responsive and kind which was much appreciated.
