It's not hard to find a great view in Lisbon because of those famous city hills. I loved views from the Park Bar and the Memmo Alfama. But I think this view, from my room at the Four Seasons Hotel Ritz Lisbon, was the best. It's built on one of Lisbon's highest hills, and almost all of the rooms have views reaching out to the water and the Castle of São Jorge.
If you don't stay, come to the hotel and take the elevator up to the running track on the roof. It's the best panoramic view over the city!
