I'm traveling in Ukraine in June. How much to book a cabin on a train from Kiev to Simferopol?

I want to have the whole sleeper cabin to ourselves and NOT share it with strangers. How much for a regular (2nd class?) sleeper cabin? What about 1st class? What's included in each class?

A place in a lux cabin costs 300 to 430 hrn (~60-85 $). There are two places in a cabin.
A place in a coupe cabin costs 80-110 hrn (~16-22 $). There are four places in a cabin.

The price is different for different trains. Usually, the less is the train's number the faster it is and the better service it has. Ticket price does NOT include additional fees you will have to pay in order to travel.

3. Cost in the second class cabin is about
94.82 -126.15 Hryvnia ( $12-$25 per person). There are four places in each cabin.
For the first class 359.96- 495.35 Hryvnia ( $72 - $100) per person. There are two places in each 1st class cabin.

Good luck and happy travel to you!
