Affordable hotel near Wyndham Grand Xian South Hotel

I would be having a meeting at Wyndham Grand South Hotel and is looking for an affordable hotel , below $80 per night .Can you recommend me any clean and convenient hotel? I am looking at Citadines but not sure if it is a good choice.

How much is a bus ride or taxi ride from Citadines to Wyndham Grand South Hotel vice versa ?
