Great location, right across from the University of Porto. We were there during frosh week so there happened to be lots of events during the week so we had free entertainment.
You can monitor the line for Livraria Lello, (the "Harry Potter book store") from the windows on the front of the apartment, we had a glass of wine and waited for it to get a bit shorter then ran out and got in line.....there always seems to be a line lol. The Majestic Cafe ( were J.K. Rowling wrote the series ) is a easy walk if you are into Harry Potter. You can walk to the river ( it's down hill ) and you can walk back up or take a tuk tuk . 1 night we grabbed a cab up and it was only 4 euros.
The beds were comfortable and the kitchen had everything we needed. There is a small corner store with some groceries & wine just around the corner, head left when you are at the apartment facing the square, ( follow the street with the trolley tracks ) walk past the cafes and it's on the right hand side.) The apartment had lots of character and we loved having the windows open in the front for a nice breeze and to listen to the city.
I only wish we had more time while we were there!
