Housekeeping did not change new bedsheet and pillowcases when we checked into the room. They merely tidy up the bedsheet and pillowcases USED BY the previous guests. The pillows emitted strong smell of months-old pillow case. Very disgusting and smelt of human sweat and oily hair smell. The blanket has lots of creases and looked like someone slept on it for days. We called housekeeping to change the pillowcases and bedsheet. When we came back to the room, only the bedsheet were replaced. The pillows were still the same used pillowcases! When we approached the housekeeper, they denied this and insisted they changed it. However, we can still spot the same stains on all the pillows! This is unacceptable practice from a reputable hotel group. Request for new pillow cases were unbelievable hard, they could not provide clean fresh pillowcases for us. Even the pillowcases from the housekeeper’s trolley felt like they were used before and simply folded back without washing. I will think twice before staying at this hotel again.
