The distance seems not in a straight line... I drawed 2 circles with km's and location i got from a fellow seeker. We choose the intersection point, what was still 329 km away... 
Hmm so it could be distance by road? Makes it even more difficult..dont know how people already managed to get right spot. What am I missing? The clue itself is easy but not enough...i will try my distance by road instead of radius and see what happens.
Honestly, I got it partly by luck. I also drew circles according to my wife's attempt and mine and actually it was pretty darn effective. Later, after a lot of "driving" on Street View eventually, after five or six fruitless attempts and searching for unsearchable, I've found it. And I was actually too ambitious and now miss this pure feeling of adventure, so keep it fresh and don't cheat! This is a really cool little game.
