We had a wonderful stay at Annick's place. The apartment is lovely, cosy, well-decorated and very clean. The location is fabulous - in the heart of the old Lisbon, in walking distance of many must-sees, but still quiet and calm. We could hear a rooster in the morning which was lovely!
The only advice we could give is to pack a pair of earplugs for the odd Saturday night where the neighbours decide to take their party indoors (to be fair, it was raining a lot that night, something that is quite unusual in Lisbon).
We would recommend Annick's place to anyone travelling to Lisbon and we will certainly be back.
