As a Loire Valley native who planted new roots in the South of France, Antoine considers the right planning, anticipation and organisation as the pillars of a unique and bespoke travel experience.
He considers the real meaning of “Luxury” and “Service” as the keystones when designing your next stay, and uses his know-how and highly personalized approach to achieve a successful holiday.
Hotelier from 2012 to 2022, Antoine worked as head concierge for Oetker Collection hotels on the French Riviera and launched in parrallel Alter[3]go in 2020 to share his knowledge and passion for traveling. He is constantly sourcing the best addresses for his travellers between the Loire Valley castles, the radiant Paris, the Côte d’Azur coastline and the snowy Alp peaks.
“The secret of enduring memories is the right combination of remarkable places and one of a kind experiences.”

Born in Paris and raised on the French Riviera, Sébastien today has built a one-of-a-kind, exclusive network in the luxury travel industry.
After a decade as concierge in the Oetker Collection hotels, including many years at the Hôtel du Cap Eden Roc, Sébastien was awarded “concierge of the year in France” by Les Clefs d’Or in 2018.
2020 was a milestone in his life as he decided to launch two companies. The first, a luxury hotel management school to pass on his knowledge and passion, the second, a destination management company called Alter[3]go. The essence of Alter[3]go is built on trust, to reassure that every wish will come true down to the last detail.
Sébastien is fully committed to delivering the best luxury service to all his clients, partners, and guests. When he is not designing tailor-made trips, he can be found on his motorbike exploring the beautiful roads of France and Italy, or hiking and skiing in the French Alps.
