We hat a wonderful stay at Constanca. We can recommend the apartement to 100%. The communication was on point (very fast and helpful). The apartement is about 15-20 min via car from the airport as also from downtowm of Porto away. right in front of the apartement there is also a bus station (bus 501) which drives to Matosinhos or to the inner city of Porto. the apartement is very clean, as also is there a laundry Service which is bring offered for 8 € at the apartement. for any cat lovers, we very Visited every day in the morning or in the evening from the cat called "Tabby" (He is very friendly). the only negative point is that the Walls are very thin, so we could here from time to time the neigbours, but that didn't bothered us very much. last point, at arrival and departure day, we could leave our luggage at the house from constanca. we will for sure come back here ^^
