Loved this flat to bits. The location is great, near the water, nearer still to the Mercado Da Ribeira, and walking distance to all the sights and sounds of historic Lisbon.
Inês and Antonio were excellent in their communication, and they really care about the well being of their guests as demonstrated by the numerous references on what to do in Lisbon, not to mention the little basket of fresh rolls and delicious jam that greeted us upon our arrival.
Be prepared for multiple flights of stairs up to the flat (which just warms you up for Lisbon's hills) and then reward yourself by taking in the views from one of the windows.
In brief, I really hope I can come back, to both Lisbon and this flat. Enjoy!
