I am trying to find out where is 春泽花园 situated but couldn't locate this place on Google Map.

I used Baidu map and searched it out. The Chunze Garden is near the crossing of South Songshan Road and East Jinsha Road, Longhu District. You may try it again.

You may plan to take bullet train by staying near the rail station - Chaoyang Station, right? If so, it is a good idea to stay nearby, but as I know, there are limited accommodations. If it is ok for you to take a fast train at Chaoshan Station, I suggest you stay near Shantou General Long-distance Bus Station where shuttle buses to/from Chaoshan Station are available.
