Ricardo's room was very nice and our trip in Colares amazing.
We were welcomed by his wife and mother and they were very friendly. Ricardo gave us a lot of informations about shops and restaurants in the area.
The sea was just a few steps away, we could go to the center of Sintra in 15 minutes by car to visit the beautiful castles around, or take the train to Lisboa.
Though the bedroom doesn't have its own kitchen, he allowed us to use his kitchen, what we didn't need to do in the end.
However there were quite some ants in the bedroom and it was tricky to keep food "safe", and the air ventilation of the bathroom was not working very well so towels were not drying completely in it but we had a drying rack outside the room. We could also hear foot steps in the room above us but nothing problematic.
Overall, our stay at Ricardo's was very pleasant and hopefully we could come again in the future.
