In my opinion,Rub is one of the most hospitable and kind hosts whom I ever knew!
His apartments are very cosy and clean,there are all facilities you would need.Flat is not far from metro station,but It’s completely possible to get to the center by walk!
From the first seconds he let me know that I can feel myself as at home.
Rub could give you any information about Porto you would need:)
I’m very grateful to Rub!
