Cristina was very kind although she doesn't speak English she brought a friend who did. The flat is nice and the room as well, even if the bed sheets were not that clean. It is important to notice that the flat is not located in the center of Porto. It is next to Foz (coast) but 15min away from Porto with the car (so you need to take a taxi which costs 7-8€). Therefore, if you want to visit Porto, the location of the flat is not ideal.
