Pedro and his family were such great hosts! We had a wonderful time in colares - the Airbnb had everything you could wish for and enough space for four people. Pedro had a collection with tips for trips, beaches and restaurantes around. The pool and the area around the house were great and we had a terrasse and private space. Pedro brought us fresh towels and sometimes even a round of shots to drink - cheers to you ;-)
The house us near praia grande and praia de adraga (easier to reach if you have your own car). Also the most western point of europe is around 5 minutes from there. There is a small supermarket in town but it is a little expensive so if you have the possibility better get to Lidl or another bigger one in Sintra.
I can really recommend this Airbnb! Would definitely come back to Sintra :-)
