First, I will give a helpfull tip for all future travelers.
The address, when used in google maps, misses the last 200 meters of the way. Which caused confusion for us.
You will find a big sign, Chalet Bondal. But the way it hangs gives room for interpretation on which road it points to.
Don't take the asfalt road to the right. Instead, the sign really does point to the somewhat dark, narrow road into the woods. It's 200 meters up and a bit twisty, but believe me, it is worth it when you arrive.
What a beautiful location! the gates open up to a very well maintained garden. With loads of blooming flowers. The swimming pool is trying to lure you in. Only to be instantly sidetracked by that gorgeous view over the light blue lake, with the tall mountains in the background, seeming to hug the lake in a gentle embrace.
The unique location means you won't be bothered with lot's of noise or people/cars distracting you all the time. It really is a place to come to rest and relax. Our host, Sofia, tried to make us feel at home. She is a lovely woman, and with a combination of english and a little german, we managed to communicate all the essentials. The appartment was very clean. Lot's of wood is used in the interior, which would not be my personal taste, but it does give you that typical mountain cabin feel. The beds were good, maybe a bit small in length. (probably a 2 meter length bed, and i'm 180) The kitchen was fully functional, although there are lot's of restaurants in close proximity. So cooking is by no means mandatory. There is also good wifi reception.
So are there no negatives?
Maybe 2 small ones.
The warm water could take some time to kick in. Once it does, it works well and it is plenty warm enough. It can just take a little time. Especially the shower had this problem. I would let it run for 2 minutes, before it got hot.
Driving to anywhere else, takes more time then you think. Because of the mountainous terrain, be prepared for mountainpasses and generally more twisty roads.
