Great app for knowing places
The app is a tourist guide by itself, with great and in some situations quite original walking routes. The ability to use an high quality, offline map is fantastic, and offers a huge help. I have been using it in several trips abroad, in different cities. The only problem is that the complete form of each guide is paid, but anyway much cheaper than any imprinted tourist guide, and with a real time offline map. Strongly recommended.
