This pension isn't well-advertised, and I think it just depends on word-of-mouth. It is a short walk up a hill from the Bahnhof (train station), very convenient to the tourist office, the beginning of the signposted walk to the Koenigssee, and it is only a short walk up a different hill to the "town" or down the main road to the supermarket. Our room was amazing. At 4€2 a night, we got a bedroom with cable TV, wonderful lighting and lamps, a private bathroom and living room, and a spectacular balcony/view towards the Watzmann. Breakfast was served when we woke up. It consisted of an egg, some meats and cheeses with bread, coffee/tea, and juices.
Heidi Gruesser (the owner who lives downstairs) is SOOOOOO nice and probably speaks enough English for non-German speakers. She prefers email reservations (pension-gruesser@web.de). I will stay there every time I return and hope you will too.
