The location is very good, it is only a 20 minute drive to Sintra and a lot of other nice places, Maria is very communicative and helpful.
In winter, be cautious, the only way to heat the place is by using a fireplace. It can get quite cold in the cabin in the winter months (we were here in the beginning of December). We asked for additional blankets and Maria arranged it straight away. The cabin is very nice in the summer, but in the winter it is cold if not heated properly.
