It was our great 3-day experience. Everything was as in description. Yacht is with with beautiful view, it is parked in comfort marine with parking, cafes, washing machines, shop where you cat rent bicycles. Close to Porto. Next to marine is Afurada - village where fishermen live. There you can eat truly tasty sardines prepared on flame.
Also we had picturesque boat walk along the Douro river and then in ocean a bit. We ordered it from our one of the best hosts Gonsao.
Highly recommended!
