Gästehaus Branders, Namlos 13, 6623 Namlos, Austria
It might seem surprising, but most GPS systems can handle this information.
Namlos is close to the German border. You do not need an Austrian road vignette to reach Namlos from Germany. You then arrive via the B179 (Fernpassstraße) or the B198.
On the B179 (or Fernpassstraße) traffic can become very heavy on changeover days in high season. As an alternative, before reaching Reutte, you can take the exits Vils or further "Reutte-Nord". From there, you navigate towards Stanzach (B198 - Lechtal). In the center of Stanzach, right after the church, follow the indication Namlos on the left.
