Mario was a really nice host. The apartment was cozy, clean, with an exceptional view and really well placed. You can going by walk to every main point of the city but also you can find a lot of restaurants, bars, clubs( night life, to sum up ;) nearby, which is a plus because you don't need to take any transport. Our stay at Mario's apartment was really nice, was thanks to that and of the Porto's atmosphere that we could enjoy the city so far. I definitely recommend that you stay at his apartment because I guarantee you won't never regret it. Thanks for everything, we hope to be back one day! :)
