All of the reviews about the steps and the rooftop are true. They are tough with heavy luggage, but so worth it. We were able to see a beautiful sunset over the cathedral and then turned to see a full moon coming up over the castle on the other side. A breathtaking evening!
Nuno made things easy for us by meeting us to pick up our bags so that we could explore the city before check-in. His communication was wonderful! Just stay there if you are fit enough to climb to the top.
