The studio was secure, beautiful, and clean. Just what we needed for a few days exploring Lisbon! We loved the walkability, the proximity to the green line (which takes you right to Cais do Sodre, a main hub), and the doner place and pastry place across the street.
The street was a bit loud but not too noticeable with the window closed.
Overall, fantastic place to stay for a studio space is Lisbon, would recommend!
