what is the best way to get to the hotel, from which city flying from US?
I would say the best way to get there from the US is flying to LIsbon.
when my wife and i visited Bussaco, we rented a car in Lisbon and drove their. There might be a better way, I don;t know.
Yes, best to fly to Lisbon and then rent a car. It's about 200km. If your local airport has flights to Porto, then it's closer (about 100km). But in any case you need a car to make the most of it.
