I've stayed at Viet fun quite a few times, it's such a great location if you are a backpacker. Right next to the famous Hanio Backpackers but you don't have to stay in a dorm and its the same price if not cheaper. You are set right in the heart of the Old quarter and every time I have stayed - I have been given lovely, big rooms. (though a couple of my friends were put in a slightly less impressive room). They include breakfast in the price and the staff are really nice, there is also free internet. I'd definitely recommend this place to anyone who's looking to be in a vibrant area, but is also looking for a private room for a cheap price (they even have one room which sleeps 5 - which was like having your own dorm but much nicer than being in a bunk bed). I wouldn't book trips from here though, they are more expensive than the surrounding travel agents.
