Great spot - right in the heart of the old city... We loved to open the windows and feel the fresh breeze blow through the apartment. YOU MUST eat at Agulha no Palheiro (3 blocks away) - Best meal of our 25 day / 6 country trip !!
The Stairs are no joke - I highly suggest very light suitcases or you will get a major workout!
All in All - a great stay in Lisbon !
