Nuno (and André) were excellent in their communication, whatever question I had, I got a reply within 5 minutes. They also provided us with local tips, and a treat at our arrival. The apartment is great: very beautiful inside and out with a lot of natural light, wooden floors. Location also perfect, everything within walking distance. And we had baby cot and baby bath available, so ideal as well.
Only downsides: heater didn't seem to work in bathroom (but no problem), and the front room is also directly at the hallway, so if you're a light sleeper: you hear everyone who's entering and leaving the building.
Eitherway, I hope to go back one day!
