A few days before we left for Vietnam I read a review on Trip Advisor about Hanoi Kids and the walking tours they did in Hanoi. From the moment I emailed them they were so obliging and made every effort to fit us in at very short notice. Our guide Bach, was a very pleasant young man who got on well with our teenage children. It was such a great interaction. Our children were happy to share insight into our culture with Bach and he told us about his life. He took us around the city explaining in depth the history and culture of Vietnam. We went to the mausoleum, the palace, the temple of literature and the prison Hanoi Hilton. He took us to a local cafe where the locals ate and introduced us to Pho and egg coffee! As this is a non profit organisation helping university students better their English I would highly recommend using their services. The guide is free however you pay for him to enter the tourist sites and donations are not expected but are welcome.
