Disrespectful staff. Unsafe room! In just one day, two different employees at different times entered my room without knocking!
One moment I was in the bathroom and the next I was getting dressed, even though the do-not-disturb sign was on the door.
When I complained to reception, they said it was an accident.
This was a very dangerous situation; imagine what they would do when you're not in the room, or worse, if they had entered while the guest was sleeping. It was my last day in Paris; otherwise, I would have filed a complaint.
