Jakarta.

Jakarta is Southeast Asia at full volume: a vast, humid megacity where gleaming malls and skyscrapers rise beside street-food stalls and colonial old towns. It is home to Universitas Indonesia and a host of large universities, has the best nightlife and dining in the country, and remains cheap by Western standards. It takes a few weeks to find your feet, but few places give you such an intense, rewarding immersion in modern Asia.

• Universitas Indonesia and universities like BINUS and Trisakti give the city a massive student population.
• Unbeatable food, nightlife and shopping, all still affordable by global standards.

South Jakarta is the social heart, Kemang, Senopati and SCBD for bars, cafés and clubs, and Blok M for cheaper student nightlife. Malls double as social hubs given the heat and traffic, so expect to meet friends over bubble tea and food courts as much as in bars. University communities and the expat-heavy south make it easy to find an international crowd, and weekend escapes to the islands or hills break up the city grind.

• Kemang and Senopati for bars and cafés; SCBD for clubs; Blok M for cheaper nights.
• Embrace mall culture, Grand Indonesia and Pacific Place are social hubs, not just shopping.
• Ask the Jakarta Studcasa group where the exchange and international crowd meets up.

Jakarta is the most expensive city in Indonesia, but still cheap globally, so budget around €500–800 a month, at the upper end of the national band. Street food and local transport are very cheap; the costs that add up are Western-style bars, malls and nicer flats. A kos or shared flat plus daily warteg meals keeps you comfortably within budget.

• A kos or room runs Rp 2–4 million a month (roughly €120–240).
• A warteg meal is Rp 15,000–30,000 (about €1–2); a cocktail in the south can be €7–10.
• A TransJakarta ride is Rp 3,500 flat; MRT fares are Rp 3,000–14,000.

Most students live in a kos (rented room) or share an apartment, chosen for proximity to campus and a bearable commute given the traffic. Universitas Indonesia students cluster in Depok near the campus; those at BINUS or Trisakti look to West Jakarta, while South Jakarta is pricier but liveliest. Use the Mamikos app and Facebook groups, and always weigh commute time over distance.

• Use the Mamikos app and campus Facebook groups to find a kos or flatshare.
• Live near your campus, Depok for UI, West Jakarta for BINUS or Trisakti, to survive the traffic.
• Ask the Jakarta Studcasa group which areas balance commute, safety and price.

Jakarta's traffic is legendary, but transit has leapt forward: the MRT runs north-south through the centre, the TransJakarta BRT covers the city on dedicated lanes, and the KRL Commuterline links the suburbs including UI in Depok. For everything else, Gojek and Grab motorbike taxis weave through the jams and are astonishingly cheap. Plan journeys around rush hour, which is brutal.

• The MRT and TransJakarta BRT are cheap, air-conditioned and beat the traffic.
• Gojek and Grab ojek (motorbikes) are the fastest way through the jams.
• The KRL Commuterline connects central Jakarta to the UI campus in Depok.

Universitas Indonesia (UI) is the country's leading university, its green campus in Depok south of the city on the commuter line, while BINUS is strong in computing and business, and Trisakti and Atma Jaya are large private universities. Teaching is fairly formal and lecturer-led; some programmes run in English, but daily campus life is in Indonesian. International offices are experienced with exchange students.

• UI's main campus is in Depok, well south of the centre, so live nearby or expect a long commute.
• Some courses are English-taught, but basic Bahasa Indonesia smooths daily life.

It depends heavily on your nationality, but for a full semester almost everyone needs a proper study visa, not a tourist stamp. Your host university acts as sponsor: they arrange a study permit and a VITAS (limited-stay visa), which you convert to a KITAS residence permit after you land.

Start early, this goes through the immigration system and can take one to two months, so chase your Indonesian coordinator for documents well before you fly. Short programs under 60 days can sometimes run on a visa-on-arrival or a B211 visit visa, but don't assume it: get written confirmation of exactly which visa your program uses.

• Full semester: university-sponsored VITAS → KITAS permit
• Start the paperwork 2-3 months ahead
• Bring a passport valid 12+ months, spare photos, proof of funds
• Short (<60 day) programs may use a visit visa, confirm first

Jakarta eats brilliantly and cheaply: nasi goreng, rich soto Betawi beef soup, gado-gado salad, sate, and the Betawi speciality kerak telor from street carts, plus sweet martabak by night. Warteg (Warung Tegal) canteens serve a full plate for a euro or two. The old town of Kota Tua and markets like Tanah Abang show the city's layered history, while malls offer air-conditioned refuge and international food.

• Try soto Betawi and kerak telor, the local Betawi specialities.
• Eat cheaply at any warteg, point at what you want and pay a euro or two.
• Explore Kota Tua (old town) for colonial architecture and street snacks.

South Jakarta is where students and expats gravitate, Kemang, Senopati and Kebayoran Baru for nightlife and cafés, Blok M for cheaper eats. Central Jakarta has leafy, upscale Menteng and the Thamrin-Sudirman business core. West Jakarta around Grogol and Kebon Jeruk serves Trisakti and BINUS, and Depok to the south is the UI student town. Kota Tua in the north is the historic quarter.

• South Jakarta (Kemang, Senopati, Blok M) for nightlife, cafés and the international crowd.
• West Jakarta (Grogol, Kebon Jeruk) for BINUS and Trisakti students.
• Depok for Universitas Indonesia; Menteng for leafy, central calm.

Escaping the city is the reward for surviving it. The Thousand Islands (Kepulauan Seribu) are a one-to-two-hour boat ride for beaches and snorkelling, Bogor with its botanical gardens and cooler air is an hour by commuter train, and the Puncak tea hills are a weekend favourite. The Whoosh high-speed train reaches Bandung in 45 minutes, and cheap flights from the airport open up Yogyakarta, Bali and beyond.

• The Thousand Islands (Kepulauan Seribu) by boat (1–2 hours) for beaches and snorkelling.
• Bogor by KRL Commuterline (about 1 hour) for botanical gardens and cooler air.
• The Whoosh train to Bandung in 45 minutes, or cheap flights to Yogyakarta and Bali.

Set up Gojek and Grab and an e-wallet immediately, as they run transport, food and payments. Build your life around your campus to avoid soul-destroying commutes, and always check traffic before heading out. The heat and pollution are real, so pace yourself, stay hydrated, and escape to the hills or islands when the city gets too much.

• Install Gojek/Grab and a GoPay or OVO wallet in your first days.
• Choose housing by commute time, not distance, as traffic changes everything.
• Carry small cash for warteg and street stalls, and a mask for high-pollution days.
