We ended up staying in Guincho Cottage just across from Guincho Studio on the same property. It was spacious with a large, well equipped kitchen and a patio with an amazing view over the valley and down to Guincho Beach. We enjoyed the quiet and laid back atmosphere as well as the great location. If you have a car going to Cascais, Sintra and even Lisbon for day trips is very easy. The friendly owners gave us delicious restaurant tips (House of Wonder was our favorite) and communication was very easy.
