We spent the last two weeks traveling by car in Portugal from Lisbon to the top and northeast corner of the country; over 2500 km. This map was vastly better than the smaller maps we had. It worked particularly well in giving us a clearer picture of what the routes would be like. We discovered no errors.
It also contains an index of cities and villages.
Not 5 stars for the following reasons: many small villages not on the map. (To an extent this is unavoidable given that there are so many small villages.) Also, there's no cross milage chart.
Even more valuable would have been a chart of estimated driving times between major cities. It was all too easy to get stuck behind (very) slow moving trucks in the hilly areas. The 'N' roads, which look like major highways on the map, usually have just one lane in each direction. In addition, they can be endlessly twisty, leaving little opportunity to pass.
