We stayed here for 4 nights, and it was perfect for us. The location is absolutely unbeatable. It is the perfect hub to get lost in any direction and experience Porto. Additionally, there are so many fun places on the street just doors down from the apartment. Do Norte Café had one of the best breakfasts in Portugal, and I had one of the best meals of my life at Elemento.
Check in was easy, and Susana and Pedro met us and gave us the tour and recommendations. They are very nice!
The apartment could use a few extra amenities, and a nice airing out (as it is very old and beautiful), but overall we thought our stay was lovely! Highly recommend.
