DO NOT DRINK THE WATER from any faucet.
It is fine to drink the water in any of the dining establishments on the premises. Rest assured that the water and the ice in the hotel restaurants and bars is filtered.
In your room, the water is NOT filtered or safe. There are two empty glass jars in each room and a filtered water filling station on each floor of every hotel building. So, simply take your jars to one of these stations and fill them as needed.
