Sheraton Xi'an North City Hotel

I only chose this hotel due to the brand. It was in a favourable location, and with my previous excellent experiences with Sheraton brands I chose this hotel immediately. However my stay was worse than any other hotel stays I have ever had in my life including 2-3 stars hotels. First, the room is filthy. There’s dust everywhere in the room, especially collecting at the corners, near doors, near walls, on lamps. Secondly, the person manning the eggs section at breakfast gives such an attitude and acts like we murdered her family. She made our breakfast experience such a poor one. Also, the breakfast is terrible!!!! We go down for breakfast around 1-1.5 hours before it ends everyday AND THERE IS ALWAYS NO FOOD LEFT. This hotel does NOT replenish dishes/fruits when it depletes so you either go for breakfast Super early or you are left with the scraps. It is so ridiculous I wonder how can the manager let this happen? I have never experienced this before. We pay for breakfast and there’s nothing to eat! Even the tea is stone cold!!! So Everyday all we drink is cold tea and we had to make do with whatever little that’s left. Then there’s one day where we had to leave the hotel early to go for a tour. We missed the breakfast so we asked to have something to take away with us. We specifically asked for some fruits e.g. banana. There are 3 of us and all we got is a little brown bag with one yoghurt, one croissant and one sandwich. Not even one banana. Lastly, wifi is unusable
