Caro Wanmancy , Thank you for choosing to Stay with Armani. Thank you for taking time to share your comment in TripAdvisor, I really appreciate it. Please accept my apology if you get the impression the staff can enter your room without prior announcement. The door bell is available outside of each room and staff will only enter the room if Make Up Room sign is on. We clearly brief our staff not to enter occupied room without ringing the bell door or calling through telephone. Please contact me if you’d like to address further concern during your say, you may reach me at swadama@armanihotels.com. Looking forward to your feedback. Grazie, Spencer Wadama
