We enjoyed staying at Claudia's lovely house in Sintra. The location is great, it's in the picturesque village on the hills and it has easy access to the road, it's also close to the local market and the well-stocked grocery shop in nearby village Amocageme.
It's right behind a nice tapas restaurant (live Fado on Friday nights is really fun!) also close to other good restaurants/cafes in the area. There is also bus stop nearby if you don't have a car, but I think having a car would be more convenient.
The house itself is very clean, basic but with everything you need. We stayed there in winter, like most house in the area, there's fireplace in the living room and separate heaters in the bedroom and bathroom.
Best of all this is a friendly village with close-knit community and Claudia is very helpful host, I would recommend staying there!
