Als Mieter in einem Mehrfamilienhaus kann ich die Milu Casa GmbH nur wärmstens empfehlen! Die Zusammenarbeit mit diesem Unternehmen ist durchweg positiv. Die Milu Casa kümmert sich um alle Belangen des Gebäudes und sorgt dafür, dass alles reibungslos funktioniert. Die Mitarbeiter sind stets freundlich, professionell und sehr hilfsbereit. Egal, ob es um die Reinigung der Gemeinschaftsbereiche, die Wartung der technischen Anlagen oder die schnelle Behebung von Problemen geht das Team ist immer zur Stelle und reagiert prompt. Besonders schätze ich die transparente Kommunikation. Bei Fragen oder Anliegen wird man immer zeitnah informiert und erhält kompetente Antworten. Besonders schätze ich die Höflichkeit von den Mitarbeitern, aber ebenso von Herrn Stulz und Frau Probst. Sie haben steht ein offenes Ohr und vermitteln falls nötig, zwischen Verwaltung und den Mietern, um das Optimum für alle Seiten zu erreichen. So etwas ist für mich als Mieter unbezahlbar. Vielen Dank für euren Einsatz
