Wow, this is a gem of a stay! If you are debating between staying in Porto and Vila Nova de Gaia, you will not go wrong staying here. The view you get of Porto over the river (day & night) is unmatched -- better than a postcard!
The bridge to walk into the city center of Porto is a couple minutes from the entrance. Make sure to stop by World of Wine if you're a wine fan as it's extremely close. Highly recommend!
