Madalena's place is very comfortable and suited our group of 4 adults and two children aged 14 and 12. It is very well situated to visit Sintra, Lisbon and the coast nearby. We went to Sintra by tram which runs through Várzea de Colares and to go to Lisbon we drove to the railway station at Portela de Sintra (excellent and cheap parking) and then took the train to the capital. It is a good place for rock climbers who enjoy bouldering as there are several areas of the Serra de Sintra where you can do this.
We found several good restaurants nearby. We particularly liked the one next to the GNR post on the road to Sintra. It's just a short walk away from the house and the people running it are very friendly and speak English. We also liked the small supermarket closest to the house.
Madalena and her family are very friendly and helpful. The children also loved their two dogs!
Our main criticism is that the description and photos on the Airbnb website do not match the available accommodation. No doubt Madalena will correct this soon.
