Von der persönlichen Beratung bis hin zur definitiven Ausführung (durch den Chef selber!) hat einfach alles gestimmt. Die Abrechnung war tiefer als der offerierte Preis, die Termine wurden alle eingehalten und die ausgeführte Arbeit verdient eine Top-Bewertung. Vielen Dank für die sehr gute Arbeit!
