Das Einfamilienhaus benötigte eine sanfte Renovation. Maler Bruno war gleich zur Stelle. Mit seiner Beratung und guten Ideen konnte er mit Farbe noch mehr aus dem bestehenden Objekt heraus holen. Die Arbeiten wurden gleich und mit hoher Qualität ausgeführt. Das Preis-Leistung-Verhältnis stimmt auch. Sollten Sie eine Malerarbeit vergeben wollen, so kann ich Ihnen Maler Lorenzo Bruno empfehlen.
