I am not sure how it works in Russia but, in the US regardless of rental agreements the landlord can not enter an apartment without permission from the tenet . Maybe they have an agreement that if someone is away they can go in to service equipment. Again,it is Russia so there may be those tenet rights. I have lived in apartments here in the US and some landlords still think they have free run of the place when they want. I want to become a paying member but if the tenets are going to fk with the cameras or hide like the Spanish girls do,I am not wasting my money,not that watching people isn't wasting money.
