Completely understaffed front desk. Several stations were not manned by staff. View overlooking the Eiffel tower (we paid extra for) was obstructed by a filthy window that looked as though it hadn't been cleaned in years. Pulled back the blanket and top sheet to nap and noticed a dark colored substance, possibly human feces on the top sheet. Called guest services and asked for someone to come up and change the sheets. They said someone would be right up. After waiting about a half hour, I called again, and they assured me that someone would be right up and resolve my issue. About 15 minutes later, a man arrived with new sheets in hand and put them down on the tv stand. He looked at the substance on the bed and said, "OMG, I'll tell the manager." He left without changing the sheets. Called back down to guest services and told them we were not changing our own sheets, asked for a manager to come up to our room. Said they have a manager from the front desk headed up right now to meet with us. We gave them another 45 minutes to show up, and nobody came. Called again, got GS Mgr Julie. Call was disconnected. Called back immediately only to be placed on hold for another 30 minutes. Hung up,called back, asked for Julie, the Manager who hung up on my wife. Julie picked right up and was very aggrivated that I blamed her for hanging up on us. I wasn't happy at her I told her that we weren't changing the sheets. Asked her why she didnt call back and help us. She had the nerve to tell me that she moved on to the next problem. She assured me that someone would be up to change the sheets. 10 minutes later, a housekeeper was in our room and was disgusted by what was on our sheets and that sheets were dropped for us to change on our own. She said she would address the manager. Our first night was ruined, and we went to bed, and we decided i would address this further on the next day. I went down to the front desk the next afternoon. Very few staff on again. The check-in line was almost to the front doors of the hotel. Went to a door where staff was exiting and entering the back room. I got the attention of an employee returning from break. He said he would send the manager out to speak to me. I waited 20 minutes, Nonody showed up. I decided to place a call to the hotel and ask someone to meet me in the lobby. I spoke to a nice young lady, Asst. Mgr. for guest services. She was in a call center at another property. I explained what had happened. She made contact with a hotel manager named Tiffany who would be right out. She said she'd remain on the line with me until Tiffany showed up. 5 mins went by and the employee exited to see of someone came out, said he would let Tiffany know I was still waiitng. 5 mins later, the woman on the line said Tiffany lied. Said she met with me in the lobby and took care of me. I left. I was done. Told the woman i would mention Tiffany lying in my review. She said would credit the over 300 in resort fees for my trouble. Day 6, Came back to room late and room wasnt serviced, Had to pickup wet towels off the floor to use for showers before bed. Beds werent made. Has to get TP from another room. All Services we paid for. Next day at checkout told them room wasnt serviced. Offered nothing but to let management know. OF COURSE, the service fees were not credited as we were told. They did eventually credit them all. Called to complain to GM and to be made whole. Put on hold and then sent back to the main menu! Ceasars should be ashamed at how this property is being run. We spent alot of money dining, shopping and gaming at your properties. TOTAL LET DOWN!!!
