San Isidro and Martínez for British Families: The School-Run Suburbs
Why most British school-run families end up in San Isidro or Martínez: proximity to British schools, leafy streets, lower rents than Palermo, and real suburban life 20 minutes from central BA.
Thomas SinclairWriter and editor · London
San Isidro and Martínez form the heart of the British school corridor in greater Buenos Aires. Located 20 km north of the city centre along the Mitre train line, these two adjacent suburbs concentrate the highest density of British-curriculum schools in Argentina. For UK families whose primary relocation criteria is education, these suburbs are often where the decision ends up — regardless of what neighbourhood they originally imagined.
Location and character

San Isidro is a historic municipality (partido) with a colonial cathedral, a riverside park (the Tren de la Costa connects here), and a mix of grand old houses and modern apartment buildings. Martínez is the commercial centre of the same municipality. busier, more shops, more apartment options.
Both feel like established English commuter-belt towns: tree-lined streets, good pavements, families walking to school, local cafes with regular crowds. The comparison to Wimbledon or Richmond is not ridiculous.
Schools proximity
The three big British-curriculum schools are all within 15 minutes' drive:
- St. Andrew's Scots School (Olivos/San Isidro border) — 10 minutes
- Northlands (Olivos) — 15 minutes
- Michael Ham College (San Isidro) — 5 minutes
School buses operate through both suburbs, picking up children within 2-3 blocks of most family homes. The school-run logistics that dominate family life in these suburbs are well-oiled and decades old.
Housing
To buy: houses range from USD 200,000-600,000 depending on size, condition. And proximity to the river. Apartments are cheaper: USD 100,000-250,000.
San Isidro/Martínez housing is 20-30% cheaper than equivalent Palermo flats for the same square footage, with the significant advantage of houses with gardens. rare in central BA.
Commuting to central Buenos Aires
Mitre train line: San Isidro station to Retiro (central BA) in 25-35 minutes. Trains run every 10-20 minutes during rush hour. The Mitre line is the most reliable suburban train in Buenos Aires.
By car: Panamericana toll motorway, 20-30 minutes off-peak, 40-60 minutes in rush hour. Toll: approximately ARS 2,000-3,000 each way.
By Uber/Cabify: USD 8-15 to central BA depending on traffic.
Daily life
Shopping. Unicenter Mall (one of Argentina's largest) is in Martínez. Carrefour, Jumbo, and Coto supermarkets are all within walking or short driving distance.
Dining. Excellent neighbourhood restaurants along Av. del Libertador and in Martínez centre. Less diverse than Palermo but solid quality for families.
Healthcare. Hospital Central de San Isidro (public). Several private clinics. OSDE and Swiss Medical operate full networks.
Green space. The riverside area (barrancas de San Isidro) has parks, running paths, and river views. The Tren de la Costa (light rail) connects along the waterfront.
Social life. The British-Argentine community is concentrated here more than anywhere else. Cricket clubs, rugby clubs (San Isidro Club is one of the oldest), school parent groups, and community events create a natural social infrastructure.
Who lives here
San Isidro/Martínez is home to:
- British school families (the core demographic)
- Professionals commuting to the city
- Wealthy Argentine families seeking quiet residential life
- International corporate relocations
- Some retirees who prefer suburbs to city centre
The international community is visible but integrated. not a "bubble". Argentine neighbours are the majority, and the suburb feels authentically Argentine with a British institutional presence.
Comparison with other family suburbs
Bottom line: San Isidro/Martínez offers the best balance of school access, commute, and suburban life without the isolation of gated communities.
Not property advice. Walk the streets at school-run time (8 AM, 4 PM) to feel the rhythm before committing to a lease.
