What is Mix?

An all-in-one hospitality concept

A unique and unusual place in Brussels. Located in the former building of the Belgian Royal in Boitsfort. Mix, totally decorated and renovated by Atelier Lionel Jadot, gathers a hotel, restaurants, event spaces and an extraordinary Gym & Wellness.

It is a place for those who want to change the way they organise their daily life, a place for those who want to join a unique community, a place for those who want to escape to a green space in Brussels, a place to boost your creativity or even to outdo yourself.

Where is Mix located?

Mix is located on Boulevard du Souverain 25 in Boitsfort. We are located in the former building of La Royale Belge.

Close to public transport, the European Community and the main roads of Brussels.

When does the Mix open?

We know you’re excited, but it’ll be a few more weeks before we open: the Mix is scheduled to open mid-June. Until then, be well!

My curiosity is too strong, can I visit Mix before the opening?

For the moment it is not possible to visit the building due to the safety requirements of the construction site, Mix will welcome you as soon as it opens in June!

As of May, we will start to hold meetings in our offices (next to the building site), and can welcome you there for more information on the Gym & Wellness and our events, visits are by appointment at

Are children welcome at Mix?

The restaurants, hotel and other common areas are open to the public, including children.

Does Mix have a parking lot?

Of course, Mix also has a parking lot for visitors on 2 or 4 wheels. The Mix car park is public and accessible to all visitors.
