We really enjoyed our stay at porto Island. The appartment is perfectly located to reach the city center (Ribeira) as well as the beach at Matosinhos within 20 min by metro. Public transportation is also really affordable in Porto (Metro ca. 1,6oeuro one-way). In General Porto is a beautiful town for biking, exploring the beach/ parks/ rio douro historic center (architecture and buildings are awesome), nightlife, good wine and food (especially fish like octopus). But the available guide you receive when you arrive at porto island will summarize the best sports Porto has to offer. The apartement has comfortable beds, a kitchen with basic kitchen equipment. The backyard gives the possibility to have a calm breakfast/ dinner without getting disturbed by a any annoying noises. It is located in a quite area, but still central.
Best Wishes and obrigado.
