I left Motel 168 this morning, they are all over Shanghai, the one I was in was near Pudong road on the No 4 subway, 138rmb per night, not too far from the city, clean, great staff, bit noisy in the mornings as the hallways are tiled but for the price I'd give it 8/10, lots of little restaurants and small shops and supermarkets in the area, cost me bugger all to live there for 3 weeks, giving Nanning a go now, much smaller and warmer, Hotel No is..021-51171111
About 75rmb to the Airport by taxi and the shower is big enough for about 4 people lol.
Edit, just asked my lady friend, it's on Dalian road about 100m from the subway.
