Max's appartement is ideally located to visit beautiful places in Sintra natural park and not far from Lisbon by train (from Sintra) or car. We had a wonderful stay, we enjoyed the amazing view, spending time in the garden and in the pool.
You must have a big car (with good suspension) to reach the Airbnb and use the app Maps or you could be lost on some "funky" et unfriendly roads in the montain.
