We stayed there as a family (2 adults, 2 children) for 2 weeks in April. The location is really great! You can see the westernmost point of Continental Europe (Cabo da Roca) directly. The sunsets are amazing. It is also very quiet. Other than chirping crickets, you hear nothing there! A great starting point to explore the Sintra region. In addition, Lisbon can be reached in about 30-40 minutes by car. Various beaches are also just a few minutes away by car. The Wi-Fi works perfectly. TV with satellite. Everything good. The landlord is very friendly and you can approach him with any concerns. He was very helpful!
One star deducted for the equipment, as it is very sparsely furnished. Definitely not luxury, but it has everything you need. It could be a little cleaner, but not really bothersome!
All in all, top value for money. We had a very nice holiday there and can recommend it!
