Please book your own hotel rooms, through your favorite site such as trip.com, hotels.com, apgoda.com or booking.com. There is a huge choice, but choose one to suit your price range somewhere in the central area, i.e. not out near either major airport. For example Hanting Hotels and JI Hotels have many very affordable locations all over Shanghai. Shanghai has 20+ metro lines and Didi taxi service so any hash location is only 20 minutes or so away.
