Everything that needs to be good about this place is great! The location: 5 min walk from the bus station and supermarket. Lots of food options nearby.
The space: Very clean, tidy and functional.
The hosts: Super accommodating (pun intended!). Allowed us to leave our bags before and after check-in, gave us this lovely map they developed which guides you through a walking tour of Porto capturing all the landmarks.
Can't ask for more. Highly recommended!
