If you value good sleep in the night, this is a perfect place out of Sintra centre. The neighborhood is silent and very little traffic on the oneway road where the house is located. As a solo traveller I felt safe in Patrcias house.
She provides an effective heater and it is possible to warm the house with it or a wood burning stove.
The kitchen has everything for cooking and preparing a breakfast.
I can recommend this place without any hesitation.
