Great space, central to everything in Porto!
As others have noted, there is construction going on and that can be quite noisy at odd times. It was difficult to find the entrance to the building for check-in and there were no instructions about how to find the place with all the construction blockages.
Also, we had to request and go get a 2nd set of keys which we needed for our 4 person group.
Otherwise, a very lovely apartment with lots of light and comfortable space. Would recommend!
