Превод - Италиански-Немски - mio caro bonnard, aspetto la vostra risposta a...

- I'm assuming "Bonnard" is a man's name... the French painter from the 19th century, maybe? And this would be a translation of a letter to him? Just speculating, here :)
- I was actually surprised by the "NON mi sta simpatico", here... makes the message sounds a bit weird. But that's what it says...
- I assumed that "tra qualche settimana" referred to "della mostra di arte". If it is connected to "aspetto", then the translation would be, I think: "Ich warte auf Ihre Antwort über die Kunstausstellung, die in Nizza stattfinden wird, innerhalb der nächsten Wochen"
