Apartment is on a perfect location: it is in the city center, easy to catch all turistic points.
Porto is a small town, we walked to every place.
Gabriela and Tiago were the best host we have ever met: traditional (home made!) Porto wine was waiting for us in the flat and they have recommended their favourite place in the city. We tried almost everthing they suggested, food, sightseeing points, beach and drinks :)
Apartment is very clean, well equipped and the garden is amazing.
We recommend to stay there and would we would book it again for sure.
