Getting from Xi'an Hotel to Citadines Central Hotel

I see from the map that there is a Nanshaomen metro near to the XA Hotel where the airport shuttle bus terminates. May I know how far is this metro station from XA Hotel? Is it within walking distance?

If we take the metro from Nanshaomen to Bell Tower station, how do we walk to get to Citadines Central Apart Hotel?

Many thanks!
