Location is 15 minutes drive/ride from Achenkirch, a standalone house on the hillside. Our navigation system (Waze) did not find the right way there but there are small yellow tables at the crossings which help (and - as always - asking the locals).
The road from the main road to the house is beautiful, romantic and can seem to be challenging at first but doable in Summer.
The landlords are a nice elderly couple, they dont speak English. The apartment was like new, modern, clean and perfect except the very soft pillows. Everything works, very nice shower, good lighting, lots of wall sockets and modern kitchen (these are not obvious things elsewhere). Mobile net works despite the location, wifi usually works too. There was a large tv with film channels (which we didnt use)
I recommend the place for those who like an accomodation isolated in the hills (end of the asphalt road), silence, fresh air, especially if you like mountain-biking our hiking. We were with car/trailer/moto, and we liked it very much.  

Sehr nette, einfühlsame Vermieter mit einigen sehr netten Gesprächen. Haben uns sehr wohl gefühlt.
