The apartment is very comfortable and beautiful, spectacular views, located at a premium location. It's a small apartment but beautifully decorated, with everything needed for a short or longer stay. It is located right next to the castle entrance, and next to two fantastic viewpoints (Santa Luzia and Portas do Sol). There are several other attractions at walking distance. The apartment terrace has a really spectacular view over the oldest parts of Lisbon, the river and the south bank. Communication the Patricia was fantastic, she gave us lots of helpful tips.
Climbing those four flights of stairs can be a bit challenging at first, but after a few days walking the Seven Hills of Lisbon it will be a breeze.
