What is a duplex apartment in Spain?

A duplex (dúplex) in Spain is a two-level apartment connected by an internal staircase.

They're popular because they offer the space and separation of a house within an apartment building.

Typically, the lower level contains the living room, kitchen, and a bathroom, while the upper level has bedrooms and bathrooms — providing good separation between living and sleeping areas.

Duplexes are usually found on the top floors of apartment buildings, often with a roof terrace or solarium on the upper level offering views.

They typically range from 80-150+ square meters.

Prices start from €100,000 for modest duplexes to €300,000+ for premium ones.

Advantages: more space and privacy than standard apartments, often with terraces, house-like living without garden maintenance.

Disadvantages: internal stairs may not suit elderly or mobility-impaired residents, potentially noisier between levels, heating/cooling two levels costs more.
