This was the worst experience I have ever had in a 5 star hotel. The lights in the room were flickering and although they removed them, the only response was "we will replace them after you check out" after 3 nights.
The bathtub was badly cleaned and was very filthy with water stains.
Also, the walls of the room were very thin and we could hear the TV in the next room all the time. I asked the staff if they could take care of this, but the situation did not change at all.
I will never stay in such a hotel again. I hope you all don't have a similarly bad experience.
