Me and girlfriend went for a short trip to Porto. This place was everything we could ask for. The location is splendid, literally next to Torre dos Clérigos and some of the most emblematic streets of Porto. Also, regarding the apartment, it is cosy, UNIQUE, stylish - and for the hammock aficcionados, we enjoyed a lot being able to stop and chill for a bit with a good book or conversations. The place and whole building was being renovated, thus the only "minor" is that you can hear your neighbours and people in the corridor but it didn't spoil our experience.
Highly recommended, would definitely do it again!
Pros: hospitality, price/quality ratio, coziness, style, location
Cons: you can hear people from the other apartments, little natural light.
