Alternative facts or fake news? Mystery Cache

Cache is NOT hidden at the listed coordinates! The riddle is tough, a hard nut to crack. Finding the coordinates will be a real brain twister. That is a promise!

In case you try your luck with this MMM (mega mysterious mystery), do not blame me for loss of time and nerves. You have been warned!

The macrolocation:

The building close to which the cache is hidden looks like a fancy five star hotel. I would give it 10 stars. It is one of the most beautiful historical buildings in Ljubljana. Awesome architecture. Believe me. It's luxurious, it's artistic, it's one of a kind.

Best place to spend a glorious night in Ljubljana. You can sleep in one of the many stylish loft appartments. There is plenty of space on the upper floors. You will be surrounded by the finest, most attractive, and richest people of the city. I guarantee you a night that you will never forget.

The cache:

It is so great and beautiful that some of you might want to live in it.
