After many wonderful years at Club Med (co-founded by the Trigano family), in 2008, Serge Trigano launched Mama Shelter in partnership with his sons Jérémie and Benjamin. From the outset, they wanted to offer their customers an enjoyable environment and exceptional service at an affordable price. They have based themselves in the cities they love, in districts that tell a story. Focusing solely on such cherished locations has enabled the founders of Mama Shelter to express their ideal of an unusual, eccentric and unique place. More than rooms and restaurants, the Mama Shelter hotels have an energy, a vibrancy; they are true urban refuges, not just aesthetic and modern, but also popular, welcoming and sexy. The Paris East hotel was followed by hotels in Marseille, then Lyon, Bordeaux, Los Angeles, Rio de Janeiro, Prague, Belgrade, Toulouse, Lille, London, Paris West, Luxembourg, Rome, Lisbon, Paris La Défense and Rennes. Future establishments are currently planned for Dijon, Dubai along with many other places. In 2014, the international hotel chain Accor joined forces with Mama Shelter to extend this concept and welcome travellers from all over the world. Mama Shelter is part of Ennismore, a creative hotel group rooted in cultures and destinations, with a global portfolio of entrepreneurial brands. Ennismore is a joint venture with Accor founded in 2021.

Combining the best of hostels and hotels, we offer a variety of accommodation including single and double rooms, family rooms, dorms and female-only dorms alongside 24/7 service, lively common areas, coworking spaces and an all-you-can-eat breakfast buffet.

Growth remains strong with recent expansions into Brighton, Brussels and Antwerp plus the newly opened a&o Firenze Campo di Marte in early 2025.

Beyond hospitality, we are passionate about education, arts and sports. Through our a&o educare initiative, we support equal access to education, while a&o Kunsthalle provides a platform for emerging artists. We also actively sponsor youth sports teams, helping to foster talent and community spirit.
Backed by investment from Stepstone and Proprium, a&o continues to expand and modernise, ensuring budget-conscious travellers have access to high-quality eco-friendly stays across Europe.
