My girlfriend and I went up to Roger and Inge's looking a nice getaway from the chaos of the city. We had a great stay and would definitely recommend to anyone looking for a nice retreat.
If you do plan on booking here are some things that might be helpful. As others mentioned, the road up is very curvy but it is manageable if you go during the day. We lost service once we went into the road leading to the tiny house and had no signal the entire time we stayed at the tiny house. They do have wifi which was spotty (especially during the day) but we didn't mind since we were there to disconnect. The house has everything you will need if you intend to make your own meals (Roger and Inge were also kind enough to leave eggs, milk, fruit, and other nice touches). It was cold when we got there but we were wise enough to take blankets and they have a heater that made our nights super comfortable. Above all else, Roger and Inge were great hosts and were super responsive.
We loved our stay and would highly recommend.
