I have been familiar with the hostel for more than 20 years, starting from the 10th grade, when we went to the regional Olympiad and lived here. Yes, it is true that there are toilets in the hallway and 1 shower in the entire dormitory, the kitchen is only on the 3rd floor. But such are the structural features of the building, there's nothing you can do about it. You can only make more or less decent repairs, but, as usual, you need a lot of money for this. Nevertheless, there have never been any problems with taking a shower, although yes, sometimes you need to wait. They offer extra blankets if it's cold. You can borrow a kettle from the staff, there is a microwave in the recreation room on the 1st floor, and there is a refrigerator on each floor in the hallway. That is, the usual household minimum is there. And the price, you know, also matches. At the moment, this is about 8 rubles a day, slightly less than 41 rubles for 5 days of stay. Compared to the hotel prices, it's for free. So for me, a solid 4 can be set (because there is always something to strive for). From the recommendations: take additional hangers with you if you take clothes that need to be hung on hangers (there are only 1 piece per person). Warm clothes in the room won't hurt. Well, your kettle (or at least a boiler) will just make life easier. There will be no need to run to the kitchen. There are also 2 sockets for 3 people in the room. So either charge the phones one at a time, or it will be more convenient to take a charger for many devices.
I was accompanied by children for a week. The conditions, of course, leave much to be desired. There is one kitchen per floor (and not for every one), a toilet at the end of the corridor, a shower on the 1st floor (shared, 3 cabins). The rooms are designed for 3 people, there are bedside tables, a wardrobe, a table.
But there are wonderful people working there. They are responsive, polite, and try to make your stay there better. You can contact them with any problem or request.
the conditions are not very good, to put it mildly: there is no repair, the wallpaper is Soviet, the toilets are generally something. But there are already 2 refrigerators on the entire floor, there is a kitchen on each floor, there are electric stoves, enameled kettles and pots. There is nowhere to heat the food, we go with plates / containers to the first floor and ask the janitor for permission to use the microwave. The only advantage: normal beds, clean bed linen, towels.
