a&o Hostels, the European hostel chain, reported its best-ever company performance in 2024 with consistent growth across guest numbers, revenue, overnight stays and new openings, according to its latest annual report.
In 2024, a&o recorded 6.2 million overnight stays (up from 6.1 million in 2023), welcomed 2.8 million guests (compared to 2.7 million in 2023), and generated £192.7 million in revenue (an increase from £179.9 million in 2023). The average occupancy rate across its European properties stood at 76.6%.
As part of its expansion efforts, a&o opened new hostels in Brighton, Antwerp and Brussels. In February, the company officially launched a&o Firenze Campo di Marte in Florence. Looking ahead, a&o will focus its expansion on major European metropolitan areas, with the Heidelberg property as the next milestone. Scheduled to open in late 2026, the five-story hostel will feature 118 rooms.
“2024 represented steady growth and has surpassed the record results of 2023 to make this the best performance in our history. As we celebrate our 25th anniversary in 2025, a&o has entered the year strongly and confidently and we remain really well placed to create and deliver long-term sustainable growth”, said a&o founder and CEO Oliver Winter.
