Fabio is a great host. He was there waiting me when I arrived, gave good explanations and left some interesting brochures about what to do in Porto. Also the booking went smoothing and everytime I had a question, a quick answer followed.
The apartment is perfect for visiting the city: very close to the station, Ribeira, santa catharina, clérigos, etc.
It is very clean and pratical. The kitchen is very good equiped (which was not necessary as plenty of restaurants and places to breakfast close by). Shower gel and shampoo are provided as well.
Next time I go to visit Porto, I surely go back to Fabio's place.
