About Trefls

Trefls is a publication about short city guides for curious travellers. Our articles aim to be genuinely useful: practical plans, honest advice and facts checked before publication.

Who publishes this site?

Trefls is published by the Hexuvium group (Singularity Group B.V.), which brings together Hexuvium, a short-term rental concierge founded in Brussels in 2015, and CyberNovaLabs (automation and AI). When we suggest staying in a Hexuvium home, it is an in-house recommendation, and we say so openly.
