Hello dear detectives! I am looking for a person, I know the phone number, I know the page in the social. networks. However, for personal reasons (not crime), contact with him and his entourage is not possible. A person lives in St. Petersburg, most likely rents a room (apartment), works in St. Petersburg most likely somewhere in a hotel in the city center. Which way should I go? Not all hotels are ready to provide information about employees, wandering around the city is not an option, I live far away.
