I stayed at the apartment for 3 nights and it was a very pleasant stay, starting from the welcoming part to the end. The house is cozy, clean, well decorated and has everything you need. In general it's well located, just behind the Clerigos Tower, close to the tourist attractions. But the street itself is on a slope of a hill, so it can be a bit difficult for some people to climb it. Well, the whole city of Porto is very hilly, so... :)
By the way, the window views are just amazing and the church bell ring is very beautiful, they make your stay even more charming.
Thank you so much!
