Mondorf-les-Bains is Luxembourg’s spa town, on the French border in the south-east. Its mineral waters, at 24 °C, are used in a spa set in a 36-hectare park, and it is home to Casino 2000, the only casino in the country.
The commune includes Mondorf-les-Bains and the villages of Altwies and Ellange, with 5,583 residents in 2026.
The park, the spa and the border position make it popular with buyers looking for a calmer setting, and with people who work on both sides of the border.

Selling your property in Mondorf-les-Bains
The usual range in Mondorf-les-Bains is wide, from €4,713 to €10,110 per m²: location, condition and outdoor space decide where your property sits.
- The right price from the start. The average was €7,283 per m² for existing apartments, but sales ranged from €4,713 to €10,110: condition, floor, outdoor space, parking and energy class make the difference. A price set too high at the start makes the sale longer.
- The market right now. Across the country, prices in the second quarter of 2026 were 2.2% below a year earlier but 1.1% up on the previous quarter (STATEC): buyers are back, but they compare.
- Documents to prepare. The energy performance certificate (required to sell), the floor plans and, for an apartment, the condominium accounts and minutes of the last general meetings.
