I was planning to visit this exhibition a long ago, and did it few days back. Interesting idea, however not finished. Museum is positioned at the Hydropark island on the Dnepr river, next to the Mlyn restaurant (huge but less than average place). For entering the park you have to pay 2,5 EUR and then you are on your own - if you have never seen those buildings live, there is no one to explain back-story or to answer on your questions. Miniatures are representing most famous landmarks and buildings in Ukraine (mostly from Kiev and Krimea region). Small tin plates on the ground will just tell you what it is, roughly where it is and when it was built - without a story why is that particular place important.
Staff was working (cutting grass and watering pathways) in the middle of the day and they didn't care are they bothering visitors.
Part of the exhibits were missing, and part of them were broken. At the back of the park, river water breached in the park area so few exhibits were out of reach.
Finishing much earlier than planned, I went back to the starting point at the park entrance.
Old fella from ticket-sales asked me about my impressions and without letting me respond, said - for this, people should pay much more(?!)...
