Where to base
Stay near Xã Đàn, VNU, or the Văn Miếu area — small guesthouses and budget hotels sit well below Old Quarter rates, and proximity to bus corridors cuts taxi spend.
Guesthouse $10–25/night

Đống Đa's identity as Hanoi's 'student district' around Vietnam National University and Hanoi University of Science and Technology keeps prices lower than the Old Quarter — guesthouses, phở stalls, and cà phê sữa đá shops all price for residents, not tourists, which is exactly the budget signal you want.
The district is dense, walkable, and well-served by cheap public buses, so you can base here and day-trip to the Old Quarter, Temple of Literature, and Hoàn Kiếm Lake without paying Old Quarter lodging premiums. Watch for the common Hanoi money leaks: unmetered taxis, tourist-menu surcharges, and convenience-store bottled water when refills are far cheaper.

Guesthouse $10–25/night
Two street meals plus one sit-down covers a day. Breakfast at a phở stall, lunch at Đống Đa Market, dinner at a quán bún chả near the universities — skip tourist menus around central temples.
~$5–8/day food
Public buses are the cheapest base layer across Đống Đa. For short hops use app-based motorbike taxis; avoid flagging street taxis without meters and pre-negotiated xe ôm at tourist sites.
Bus cheap; ride-hail typical short-hop
Đống Đa Temple, Văn Miếu, Van Lake walks, and university campus strolls are free or nominal entry. Save paid entries for One Pillar Pagoda and Hoàn Kiếm day-trips.
Free – nominal
Unmetered taxis, 'tourist menu' surcharges, bottled water at convenience stores when refill stations charge a fraction, and souvenir markups at Đống Đa Market — always negotiate non-food goods.
Avoid
Oct–Dec and Feb–Mar offer the best weather with shoulder-season hotel rates. Avoid Tết (Lunar New Year) when guesthouses spike and intercity transport sells out.
Oct – Mar
