Really nice hotel, I had two bedrooms two bath apartment, it was very clean and comfortable apartment. 
But I think the Expedia site was misleading. There are two same brand name hotels in Xi’an, one is in center city, one  I stayed at 15 minuets away from the central city which is quite and less crowded from tourists. Expedia used the center city site characters  to advertise the remote one, or at east didn’t specify the total information is based on the one in center city. 
When I chose my hotel in Xi’an, I was thinking close to center city, which close to lots of tourists sites. So based on the information Expedia provided, I booked the hotel I thought was in center city. ¥16-18 cheap taxi ride to center city was not too bad, I stayed a less crowded and quieter area which close to a University .
