Place was nice, clean inside with good water pressure and cute kitchen area. Bed was comfortable and the rooms were a decent size.
Getting into the room, you have to climb up these super narrow wooden stairs. So, if you have more luggage than arm strength or if you are disabled in any way, this is gonna be tough. It took me 15 minutes to get my luggage all down the stairs (one large rolling suitcase and a back pack) as I was checking out. Oh and btw they count floors as ground being 0...
But the area is nice! You are right next to this big cathedral and it is next to a main road with easy access to pretty cool areas. Not a lot of noise at night on this street, lots of tourists walking through so it usually felt safe enough. Keep in mind that there is no AC and Porto gets humid heat. The fan was fine but it wasn't centered over the bed so didn't really do much.
My biggest issue was the place was that I had to be really thoughtful when opening the windows at night. I was sat at the table playing on my phone one night when I heard whistling and looked up to see two men filming me from the cathedral. This was at like 11pm. And I wasn't even naked! Da fuq. Of course this may not happen to you but there is a clear view into the room from the tourist attracting monument. Just be aware.
