This is a hotel, so not really an airbnb but there aren't many authentic airbnb options in Hanoi anyway. Location is great in the old quarter. The building is old but the rooms are as clean and fresh as they could be. The staff are exceptional and go out of their way to be friendly and helpful. The breakfast is also great - your choice of eggs, pancakes or pho as well as a range of other items including fruit, toast etc. Great option if you're looking for a cheap, reliable base for your stay in Hanoi.
