We spent around 300 yuan and over two hours trying to find this hotel. No luck.
Didn't even get to stay, ended up booking a completely different hotel back in the centre of Xi'an - highly recommend Skytel.
It is cheap and relatively clean. The location is OK. No "european" travelers at the time we were there. On the whole, I'd recommend to fly in, see the Warriors, and fly out without spending any time in Xi'an.
