About Us

The General Directorate of Tourism of the Ministry of the Economy of the Grand Duchy of Luxembourg awarded our hotel the EcoLabel Gold!

We are very pleased with this certification and this recognition for our ever more environmentally friendly practices.


In beautiful, peaceful surroundings on the edge of the forest in the heart of the Mullerthal region, Isabel and Philippe Boulliat have transformed a former water mill into very special retreat, combining an eco-hotel and a gastronomic restaurant, in perfect harmony with nature and with the seasons.

In a calm rural setting on the edge of the Mullerthal forest, the hotel grounds are still home to the pretty burbling stream that used to power the old mill and a flower-filled terrace for guests to relax.

Preserving the wonderful natural environment that surrounds it is central to the Au Vieux Moulin philosophy and the hotel is a pioneer in eco-friendly hospitality, creating an environment that is stunning, but also sustainable, thanks to cutting-edge energy and water saving initiatives.

In the restaurant, Philippe creates exquisite seasonal dishes, using the very best local produce, including game, fruit and vegetables and fresh fish.

We are pleased to announce that our hotel is now listed according to the new Luxembourgish classification of hotels in the 4 stars category.
