Porto is an amazing city, and the B&B is just next to the heart of town. From that position you can easily reach and visit both sides of the Duero river. The apartment is clean, has a fridge, tv (we haven't used it), and the check-in goes easy with door codes and by following the instructions that come by mail. Even ear corks were available, but I habe to admit there was not so much noise on the street so we didn't use them. The space in the apartment is really big! After the checkout I realised I've left my jacket in the room: I called the emergency number and someone really nice immediately came to take it out. We loved Porto and we loved Innvict Astern!
