Me and my family already stayed twice at Casa Romão. I can only recommend staying at this house. The house is very clean and has all the amenities for a prolonged stay (dishwasher, clothes washer, kitchen, etc.). Newcomers beware that phone signal is not always optimal (at least for my Portuguese operator, Vodafone), and there is no internet in the house, but if you want to disconnect from the world a bit that's not a problem at all. The garden was great to relax, and for us with kids it was great that the house already had a large set of toys (kids like new toys, yay!).
The village of Moledo is very quiet, and we never had any noise from neighbors of the house. As long as you have a car, the location is very good as a base for sightseeing: there are great beaches some 10-15 minutes away, a paleontological park/museum (Dinopark), archaeological sites (Lapa do Suão), plenty of great places for birdwatching not more than 30 minutes away (Peniche, Atouguia da Baleia, Paul de Tornada, Lagoa de Óbidos), and nice historical cities like Óbidos.
