The flat is absolutely perfect situated in the centre of Porto, close to the pedestrian zone. Mario did send a detailed plan before arrival and the key was accessible to us even though he was not there personally. The flat was very clean with a good stocked kitchen and a nice bathroom. And the breakfast the next morning is really recommendable, though we stocked it up a bit, but still worth to go! We had a very nice time wandering around in the evening and staying over in his flat!
