First of all, the traffic in Guangzhou is convenient, and the subway can go directly to all the places you mentioned. Now the subway network in Guangzhou is very developed, so taking the subway is the first choice for Guangzhou tourism. Secondly, the places you want to go are basically on the No.1 and No.3 subways (these two routes in Guangzhou are deadly and super crowded. Furthermore, as for accommodation, I personally suggest living near the subway, because most of the scenic spots and transportation hubs in Guangzhou are accessible by subway (the importance of a large subway in Guangzhou is self-evident). soso, as long as you live where the subway exits, it&;s fine (within 200 meters, don&;t go far, it&;s really a factor to take care of your children), and the transportation is convenient (don&;t choose around the railway station, it&;s crowded).
