Does anyone know of any downloadable maps for Strasbourg, ones that can be used offline, on either a android tablet or a itouch? My daughter is studying in Strasbourg this semester, and wants to feel more confident exploring the streets on her own, but doesn't have a smart phone with her, so it would have to be something she could download before leaving home. Free would be great, but not necessary. As an alternative, does anyone have any suggestions for a pocket 'hard copy' map or guide, she might be able to pick up in Strasbourg? Thank you.
