A stay in Palacio StAnna is exactly what Maria promises: a great place on a quiet spot, on a short walk's distance from all Lisboa's (other) pleasures. My room 29, on the 2nd floor, offered the prettiest view towards the Castello and the sunlit city. Accomodations are basic but provide for everything you'd need. Maria, Julia and Carlos smoothly run a clean and pleasant place and will make you feel welcome with their friendly hospitality.
Make sure you get a tour around the Palacio and see her in all splendour, you won't believe your eyes! :-)
