There is a constant calling of “guests” at the entrance.

In order not to be caught by calls by strangers, you just need to ask the master to change the house code of your apartment to a number greater than the apartments in the entrance.

For example, I have a house code 99, despite the fact that the number of apartments in the entrance is 80.

Since the change of code, I have not had a single unnecessary call.

PS, by the way, the master did this job absolutely free of charge.
