I am travelling to Dongguan and would like to stay in central area going to Nancheng District

Where is the best place to stay. If I am in the city centre and need to travel 17km how much is a taxi fare or to Houjie town which is 38km from city centre. I need to be in the home decor district. i will be taking the ferry from Hong Kong to DG. Until what time is the First International Business Centre open?
