This place was excellent. Easy to find, easy to access (digital keys meant that we didn't have to share keys between the three of us and allowed for much greater freedom), and a great place to chill in with a comfortable lounge and Netflix on the smart tv remote (such a great addition to options after a long day of playing the tourist). Clerigos Tower was literally out the front of the building and the famous Livraria Lello was just about 100m away.
It was quiet and, in winter, it was warm. Well worth staying in.
