Apartment was very well placed, near the center of Porto, very good spots to eat and drink within a 5 mins walk. Neat and tidy, bathroom with a big bath tube, big windows that let the sun in, on the 2nd floor which is good.
Jay (the son) communicated very well with us and let us know that he was available at all time if necessary. Very quick to answer to questions. Hopefully for us, we didn't have any emergency that required his assistance :) Would come back anytime !
