Mario's apartment is simply great! It is located in a historical building, really close to Torre dos Clerigos, just need to open the window :) and living there even for few day makes you feel lucky.
The apartment is well furnitured, equiped with everything you need. Mario give us when we check in a bottle of porto wine, thank you Mario!
The windows, once closed, were sealing perfectily the rooms from the noise of streets.
All in one, I strongly recommend this apartment and hope I will have to chance to stay there again.
