Fantastic hosts; Cristina met us at the apartment to personally welcome us in. It's in a fantastic location for all the best eating/dining spots (10 min stroll), and a great place to base yourselves for exploring Porto.
The kids LOVED their "treehouse (mezzanine) bedroom" and the AC kept the bedrooms comfortable at night.
If visiting a port maker is on your list of things to do I can highly recommend touring Quintos dos Corvos across the river - fascinating insights into the history and process of port making from the perspective of a small family-run business, steeped in tradition. We'll be back!
