Wir verwalten unsere Liegenschaften seit mehr als 12 Jahren vertrauensvoll über die Firma Beatrice Fronczek Immobilien GmbH. Wir sind mit der Kompetenz, des Engagements, der professionellen Flexibilität und der Umsicht von Frau Fronczek sehr zufrieden. Die kommunikativen Fähigkeiten und das Fachwissen sind auch in diffizilen Angelegenheiten überdurchschnittlich. Aufgrund einer Empfehlung seitens unseres Architekten sind wir damals auf diese Verwaltung aufmerksam geworden und werden auch in Zukunft sehr gerne auf die wertvollen Dienstleistungen von Beatrice Fronczek zurückgreifen.
