Hanoi, specifically the Old Quarter is super busy so watch out you don’t get hit by a motorbike whilst trying to cross the street. The nightlife is great, lots of bars and the streets are totally packed with stools and people eating in the street. Many hostels offer free beer and pub crawls, as well as free walking tours and so there is always something fun going on in the Old Quarter.
We stayed in the Old Quarter and for just $2 a night, the Hanoi Central Backpackers hostel was a great stay for us. The best street food ever, all the streets are packed with stools and people eating local dishes which are absolutely delicious!
