We had a wonderful experience with our guide Sole, who took us around to learn about the city, its history, and the secret spots for the best food and drink in Hanoi.
The tour was perfectly planned with just the right amount of breaks strolls through the alleys and visits to the main sights all this was done with excellent Italian (using the subjunctives like even we Italians don't know how to use!) and a great sense of kindness and friendliness.
