We had a great stay at Luís lovely apartment.
He is not the kind of host that 'has' to do it but he just wants to and that is what makes the difference. He was really kind, welcoming and funny (extra; he looks like Pep Guardiola). He send us a lot of recommendations in the area and was of great help getting around in Porto. His apartment has everything you need for a couple of days.
Thanks again Luís!
