What a lovely place! First of all - it is beautifully done, clean and comfortable with almost any amenity you could wish for. The location could not be better for touring Lisbon - everything in walking distance. Despite it's central location, it is quiet! Newly remodeled building with elevator and quality windows/fixtures, etc.
As for the host - excellent! Responsive, helpful and so very nice. I have been fortunate to have very good Airbnb experiences -- but this is definitely at the top of the list!
