Visited Xi'an on a work/play trip and the local hosts selected the hotel for us. We were a little apprehensive, as the Days brand in the US would not be our first choice for hotel. This property was recently renovated and looked brand new. Beds were comfortable - an important note!
It is odd that the ground floor entrance is an empty space with the bell stand and you take an elevator to the 4th floor for the reception desk. But after you do it once, it's no big deal.
Only gripe is to get the air conditioning cool, we'd have to set it to 5C to get the room to feel comfortable.
