Good afternoon Michael , we provide a special map, an application to follow and we rent over 100 vehicles a day, no one ever has any problems, we often use headphones or simply use GPS for the passenger. You probably need a guide, but consider that they are building the new TRANVIA, i.e. the metro and therefore in these six months every road is temporary, but it does not depend on us and it is very incorrect to penalize the company that has helped you in every way for a personal problem,
