Rui was a friendly, attentive and accommodating host who welcomed us personally. We spent 10 days in the Casa do Mercado. The apartment is spacious and well equipped.
Work-and-travel side note: We were able to work very well thanks to the fast and reliable internet connection (200 Mbps and more).
We have learned to appreciate Vila do Conde in the short time: beach within walking distance, good infrastructure, many restaurants and the metro connection to Porto allow a variety of activities even after a remote working day.
Little downside, the noisy traffic (lots of ambulances and motorcycles / bikes) has already been addressed by other guests. With shutters closed, the noise is tolerably muffled.
