Answer rapidly by message. At first, the wifi was not very fast or it always disconnect but we found out that it was like that when we were in the living room. It works best when we were near a window. Other than that, good host and excellent location near all the touristic places by feet.
Claudia and Joanna got us good tip for parking places.
We were 4 friends coming from spain by rental car and a passenger in the street said to us that it would be better to park in a inside parking because often, cars that are not from porto would be vandalized if park in the street so infante parking was really a good choice.
