We had a very nice stay in this very typic small apartment.
It is very nicely furnished, the bed is comfy, big refrigerator in the kitchen, and the views from the small Rooftop terrace were simply breathtaking.
Also, the area is very nice, and the welcome manual has so many good tips.
A personal recommendation: try the restaurant 'Sud Lisboa' at the banks of the Tajo River, to enjoy a drink or meal with great views on the river.
