Mario is a very friendly, polite, interesting and reliable person. All along he cared about my arrived and my stay in Oporto. It was such a pleasure to meet him and have breakast with him.
The aparment, located in a beautiful building, is very nice, comfortable, bright, charming and fully equipped (much better tan you can watch in the potos).
It's location, in the centre of Oporto, is perfect to explore the city. Although you can go on foot everywhere, Bolhao Metro Station is next to the house.
To sum up, Mario's aparment is the perfect place to feel at home and enjoy the amazing city of Oporto. I'd recommend it to everyone.
