About Amalthea
The best opportunities on the Costa del Sol are rarely listed.
They are shared — with the right people, at the right moment.
- Local presence
- International experience
- Independent advice
Amalthea was founded by Sébastien and Irene, bringing together international investment standards, deep local knowledge, and in-house legal risk management. We arrived with a clear premise: serious buyers do not need more options — they need the right one, strictly audited, legally sound, and worth their time.
Unlike traditional brokerages, our legal and planning due diligence starts before an asset ever reaches a client. We apply rigorous risk screening to every villa, land parcel, and off-market opportunity, ensuring that any property we present has already cleared strict regulatory and structural criteria. And when a transaction requires additional technical depth, we draw from a curated network of independent specialists.
We are here to ensure you navigate the Costa del Sol market with complete clarity, protected by institutional rigour at every step.
