The place was mint-clean and well-equipped with everything one may need. The location was great as well, only a 5-minute drive from center of Sintra -- the place has fairytale-like view from its backyard to Pena palace. In addition, Rui was a great host and provided us with very useful tips as to where to eat (there are two excellent nearby Portuguese restaurants!) and what to do/visit.
We were two families staying @Rui's place and had a great time.
Definitely recommend the place!
