I found this place on a whim but felt lucky I did because I really enjoyed my stay. I used the dorm room when I there and it was really nice. The beds are comfortable, the rooms have good AC, bathroom was clean and they have large lockers. The locker was big enough to fit my entire backpack.
Free breakfast in the morning was legit.
Also the staff are all really cool and nice. Never felt bad asking for directions or recommendations on where to go.
My favorite was the bun mi cart in the front of the Hostel... 4 real, best bun mi in Hanoi!
When I come back to Hanoi, I'll be staying here again.
