When we were in the room, one of the cleaning lady...

When we were in the room, one of the cleaning lady came in without knocking and started cleaning the room even when she noticed we were inside. When I asked her to leave, she just kept doing her work and simply answer no English. She already noticed that we were inside the room when she brought us the towel we asked for 5 minutes before she came in and clean. I do not think this kind of harassment should happen inside a five star hotel like la tremoille and I would not stand this kind of impolite behavior. I really enjoy staying in the hotel the first few days, but this issue forced me to reconsider the probability of staying here again. Especially having no privacy when staying here. I called the reception desk right away, but I did not get a satisfying answer, so I hope someone from the management level can give me a reasonable answer, instead of something like "I know and I will let her know"
