Old Soviet recreational facility. only for those who feels nostalgic for USSR. Buildings, furniture and the way the facility functions hasn't changed since seventies. Poor value for money. Consider other hotels e.g. Korston instead, they sometimes provide similar prices when booked in advance.

A former pioneer camp converted into a "sanatorium" with all the pioneer amenities. I won't say about summer, but winter "rest" is guaranteed by slalom on icy paths (if you haven't broken your hip yet, but you really want to, you can try), hardening in stuffy unventilated rooms and a shared toilet. The walls in the cells are made of cardboard, and therefore all the sounds made by neighbors at night and the continuous flow of the toilet tank can be heard. The setting is typical of a nursing home in a forgotten province.
You won't have to take a walk in the forest, because the paths will be covered with snow.
There are no complaints about the dining room - you will not die of hunger.
The bus runs to Serpukhov 3 times a day, the schedule is inconvenient, but you can take a taxi for 350 rubles.
The general impression is that they are forcibly trying to return you to your Soviet childhood, but you do not want to go there. Withstood 3 days.
