Lovely flat and a great location. The area the flat is in is really quiet - if you're looking for being in party central Barrio Alto but if you want somewhere relaxing and peaceful, but still with lots of restaurants and things around, and close to lots of main sites like the castle and cathedral.
Margarida was lovely - she gave us a 'tour' of Lisbon through some maps, describing each area, places to go, tips, and lovely local information. She also got us fresh Pastel de Nata and bread ready for the morning! Lovely touch.
