On the map this hotel is about 900m away from the Lanzhou West train station, but I would advise you to take a taxi/ride-hail vehicle if you have large/heavy luggage. You have to either cross an overhead bridge without lift to reach the hotel, and because the stretch of road has buildings beside it that are undergoing construction, it can be a bit difficult to navigate the footpath which sometimes spills over to the road. Alternatively, you can take the metro for one stop and backtrack, but you would have to put your luggage through the scanner, let security test your liquids in the luggage, etc.
There is a convenience store outside the hotel, but otherwise there isn't much shopping to be done. The location is good only because it is near the train station.
