Ciao a tutti!

Let me get straight to the point. I asked a professor for a colloquio, having a hectic schedule, he asked me if next week would be alright and now I'd like to accept it but then I realized I don't know how to do that formally in Italian. I was thinking something like "Settimana prossima mi va bene" but that sounds like something I'd reply to a friend. Qualcuno gentilmente mi potrebbe dare una mano? Grazie!
