I loved historical homes and this one was very interesting. It was beautifully restored, yet it's pretty small and doesn't take too long to visit, Don't let that stop you. I visited it with my guide from Hanoi Free Tour Guides and she told me that it reminded her of her grandparents' house (but fancier).
I also visited the Enthnology Museum with a guide from Hanoikids who also told me that one of the homes we visited was like her grandparents' home. It was difficult for me to picture but later on I visited some villages and the residents still lived in traditional homes like toe ones on display.
