I can only repeat what the previous guests said: Sintra is a wonderful place and Carlos' house is one of the best places to stay during your visit. We stayed for three days and we wish we had more time. The cottage is very beautiful, nicely decorated, spacious, very clean and it has all the amenities one may need. It is located 10 minutes from the village, which means that you avoid the touristic crowds, and the route is also very enjoyable (the way up is a little bit hard, but you are on a mountain so it is totally ok). Carlos and Madalena are exceptional hosts, very kind, friendly and helpful, they even picked us up from the train station. They also provided us with several tips that made our stay much better. I can undoubtedly recommend this place to anyone without any hesitation and I would be glad to visit again in the future!
