This is a lovely house in a lovely village, and our familiy of 8 grown-ups/teenagers really enjoyed it. The beach was much better than expected, and there are plenty of other beaches in the area. My parents do not travel a lot, so they really enjoyed exploring the village, running tracks and local mini markets much more than a stay in a hotel in a more touristy place would have allowed them to. We rented two cars, which was really nice for exploring the many sights in and around Sintra - but please arrive early for the main attractions, they are magical in the morning when it is quiet, but become very crowded later in the day.
On the day we arrived, we got a lovely welcome and introduction to the cottage. Lots of tips about the area and some nice bread, wine, jam, fruit etc. so we didn't have to go shopping right away. We would love to come back some day!
