What was listed
The 2008 listing described a hostel “in the heart of Hanoi’s historic old quarter”, five minutes’ walk from Hoan Kiem Lake, with dorm beds from about $4 a night. The address was 45 Bat Su Street, Hoan Kiem district.
What is there now
Booking sites show other budget accommodation at 45 Bat Su in later years, including a hostel called Hanoi Lotus Hostel and, more recently, a small guesthouse called Thuc @3am. Hostels in the Old Quarter change names and owners often, so check a current map and reviews before booking anything at this address.
Where to stay instead
The street is in the Old Quarter, a short walk north of Hoan Kiem Lake. For a sense of the area, see the Old Quarter guide, and for the other parts of town (the French Quarter and Tay Ho) see the Hanoi guide.
