Duques Villa is a very comfortable place to stay in Lisbon. We enjoyed our time here. The views are good, the furnishings are great, and checking in and out was really easy. I would recommend you stay here if you are looking for a laid back spot in Lisbon, outside of the hustle and bustle.
The only negative thing about staying here was the distance and the ability to get to attractions without a car. Ubers and other ride shares would not pick us up here or it would be a very long wait. There is plenty of access to bus stops within a 10 minute walk, but it is something you need to plan for.
