João's place is very centrally located, about 15 minutes walk from the river, and right by many cafés, a market and a shopping centre. We were greeted by Sara, who got us settled and gave us some tips about Porto.
The decor is vintage, and there's a pleasant common area to sit. There's also a great terrace/balcony where you can sit and eat when the weather is suitable.
Overall, a nice place to stay to visit Porto.
