I did this tour with 2 friends a year ago and I was really impressed. Went to Hanoi with family this time, and I booked the same tour with Ms. Anh, the founder of Hidden Hanoi, the same lady who did the tour for us the year before.
This tour is a MUST. If there is one tour that you should do, this is the one. You get to tour the Old Quarters by walking around, and the guide explains why houses in the area are so narrow and tall (it's because of ancient tax laws based on width of the frontage!). You get to see a house from the old days and how people lived then, AND you get to see a typical house today, where 5 to 8 families are cramped into such a tiny space. There is an explanation of how business is done in the Old Quarters and the tour ends by each of you riding a xich lo (the bike rickshaw) to have a tour of the Old Quarters.
