I had an unpleasant conversation with old lady who are living in the neighbouring apartment.
I was told that this apartment is not allowed for rent and house council doesn’t approve when tenants are living there.
I payed good money for your apartment and therefore I don’t want to discuss with neighbours that I’m not allowed to live there.
I contacted with the host and he assured me that everything is ok, but it is better to use technical elevator and not meet neighbors. Problems with neighbours make me feel uncomfortable.
