The hidden gem of Hanoi is always on the bucket list of honeymooners. It is so intriguing with a long-standing history. For those who have never been in Hanoi, they will surprise why the couples spend their honeymoon here. No blue sea, no dramatic mountains or charming sandy beaches, still, Hanoi keeps its own "secrets" that can's be found anywhere else. Holding hands walking on the colonial building- lined streets in the autumn of Hanoi with the aroma of milk flowers embracing both of you is absolutely a unique memory.
