The flat I to recommend if you only stay for a night or two, it's small for two people and more a place to just sleep rather than a place to relax when it's raining and you don't feel like exploring the city.

Sadly there is mould fungus in the bathroom, which you can already smell when you enter the apartment.

At night it's really loud in the apartment as the window is towards the bar area of Porto and the windows are not proper sealed. If you have a light sleep I wouldn't recommend it.

Otherwise the apartment is located right in the center, close to pubs, restaurants and the main sights of Porto.
