Constansa's blue cottage is very cozy, kitchen has all the tools u might need, she is attentive to the details, I can see that from how the location is arrange. It might not be super spacious but it has everything you need. She let me use her grill and even lent us the coils and Gaseline blocks to start the coils.
The place is a walking distance from the beach, u will enjoy the walk in the little streets with the nature views. There is even a fantastic hair salon about 10 minutes walking.
You will enjoy your stay in a calm place whilst exploring the seaside of Porto!
