Miguel is a master communicator: timely responses and clear information made up for a smooth experience in this place.
I found the apartment to be incredibly well located, some 300m walk from the Bolhão metro station and rua de Santa Catarina, where the pedestrian-only shopping area is.
Just around the corner is Velurb, a bike rental shop owned by Sr João, a passionate bike advocate and incredibly friendly person. Get a bike there to explore the river estuary, both North, towards Matosinhos, and South, along the beaches of Vila de Nova Gaia. You can put the bikes in the metro in case you don’t fancy pedaling your way back to the apartment.
I strongly recommend this place.
