Everything is exactly as described in the listing. It’s the perfect location if you enjoy mountains and ocean. It is so green up there compared to other parts of Portugal!
We rented eBikes from Park E Bike in Sintra. We used them as our only form of transportation and got around everywhere we wanted to go. And, the Portuguese people were surprisingly not at all jerks about cyclists being on the roads with them. (We are NOT very fit people, but we managed over 200 kilometers with the eBikes. You don’t need to rent a car and fight the scary narrow roads.)
