Accor's operating and brand franchising arm HotelServices has reported a 7.6% rise in like-for-like revenue to €290m (£209m) for the first quarter of 2015.
The growth was recorded in the majority of its markets, with Northern, Central and Eastern Europe (NCEE), excluding France/Mediterranean, up 8.8%; Mediterranean, Middle East, Africa (MMEA) up 7.5%; and Asia-Pacific (ASPAC) up 7%.
There was a slight slowdown compared with Q4 2014 in France (up 6.5%) and the Americas (up 2.2%).
Meanwhile HotelInvest, the hotel group's ownership and investment arm, which launched in November 2013, reported a 4.8% increase in quarterly like-for-like revenue to €1,055m (£761m).
Accor said there was strong growth across all regions, notably NCEE (up 6.4%) and MMEA (up 7.3%), and to a lesser extent the Americas (up 3.5%), where growth was slower than in Q4 2014.
Accor opened 47 hotels or a total of 7,238 rooms in the three months to 31 March 2015.
Sébastien Bazin, chairman and chief executive officer of Accor, said: "Accor enjoyed strong momentum in the early months of 2015, making progress in all our markets and all our segments. We benefited from the initial restructuring measures carried out in 2014 by HotelInvest and also took advantage of better macroeconomic trends in most of our key markets.
