Hoi An
Hoi An is a well-preserved and peaceful city located in center Vietnam, very much appreciated by the travelers. Unsurprisingly, Hoi An is listed as UNESCO Heritage site. The only way to get to the traditional town is by road so the traffic and pollution are almost entirely absent. Hoi An is traditional and has preserved old merchant houses, temples and ancient tea warehouses. The historic town is also close to some wonderful beaches.
