As others have said, the space itself is clean and beautiful, and Max is kind and attentive. The Airbnb is a destination in and of itself. One could spend days reading, relaxing, swimming and grilling there.
What it is not is an easy jumping off point for touristic activities — especially if you do not have a car. Taxis and Ubers are not always willing to pick up or drop off up the mountain so plan accordingly. We came to Colares on a tour from Lisbon and our tour guide was kind enough to drop us off near Max’s place. On our way out of town, it took over 90 minutes to secure an Uber, resulting in us missing a train.
That said, the spot is incredibly special, full of beautiful plants and a wonderful cat named Bella. We enjoyed our short stay.
