It's fine, you can spend the night. I didn't really like that they asked for 5 rubles at the check-out for cleaning the mat at the front door in the room. Supposedly we got it dirty. They did not argue, they stopped by at night and did not look at what kind of mats they had.
The administrators are very responsive to every request. Clear. The TV in Suite 5 is the worst I've ever seen. Therefore, do not turn it on so as not to get upset .
