Quality of life
San Diego is the second district of the canton of La Unión, in the province of Cartago. It is an inland district of modest size, and it sits next to the canton seat, Tres Ríos, along with several other districts. The pack shows houses, apartments or condos, and lots and land listed for sale, and houses listed for rent, so the housing stock is mostly residential.
Before moving, check the practical details of the specific street: how reliable water service is, how much traffic noise there is, how steep or narrow the access road is, and how far you are from the services you use every week.
Cost of living
Housing is the main driver of costs here, whether you rent or buy. Property type, size and the exact location within the district will change the price more than anything else.
Beyond rent or a mortgage, build a budget that includes utilities such as electricity, water and internet, daily transport or fuel, and, if you buy, the annual property tax paid to the municipality. Apartments and condos can carry monthly condo fees, so ask what they cover. When there are enough listings, this page shows above the typical rent and purchase figures for the zone.

Lifestyle
San Diego is an inland, largely residential district within the Greater Metropolitan Area, so daily life is closer to suburban than rural or beach-oriented. Errands, paperwork and larger purchases are usually handled in the canton seat, which is very near, and the municipal offices of La Unión serve as the local authority.
Because the listings include houses, condos and lots, the district mixes established homes with room for new construction. Visit at different times of day to see how the neighborhood feels on weekdays and weekends.
Climate and nature
San Diego is not coastal. It lies in the central highlands of Costa Rica, where the year divides into a dry season from roughly December to April and a rainy season for most of the rest of the year. Rain usually arrives in the afternoon during the wet months.
Highland areas are generally cooler and fresher than the coasts. Conditions can vary from one slope or street to another, so ask about humidity, wind and drainage when you visit a property in the rainy season.
Economy and opportunities
The economy of this part of the Central Valley is based mainly on services, commerce and employment in the metropolitan area, with some farming remaining in the wider region of Cartago. The pack lists no specific employers, so check job markets directly.
Being close to San José and reasonably connected to the international airport matters for commuting, remote work that requires occasional travel, and access to universities and offices in the capital. Still, the daily commute depends heavily on traffic, so test it before you commit.
Accessibility and location
San Diego is district number 2 of the canton of La Unión, in the province of Cartago. Its postal code is 30302 and it covers 8.1 km² (3.1 sq mi).

Tips
Drive the daily commute at different hours, including the morning and evening rush, to see what it really involves. Visit the property on a weekday and on a weekend, and in rain if possible.
Ask about water and utilities for the specific property, and request recent bills. If you rent, insist on a written lease under Costa Rica's General Law of Urban and Suburban Leases (Law 7527). On Anuntico you can save listings in the zone to compare them over time.
