Great four days with my son. We enjoyed every hour and explored different areas of Porto. Would recommend if you are staying for more than two days to go to Boa Vista, escape the crowds in old town and enjoy the green areas and modern architecture in Boa Vista. Lunch at the Market bom Successo is a must, we loved Casa das Bolas- bakery and coffee shop at Av de Boavista. Best dinner was at O Ernesto - old typical restaurant in the centrum.
