AccorHotels-owned upmarket rental brand OneFineStay is targeting corporates as part of an ongoing expansion plan to reach beyond high-end leisure travelers.
The agreement comes amid a series of high-level exec changes taking place at the UK-based OneFineStay.
More than 1,000 of the site's properties in locations such as London, Paris, New York and Los Angeles will be included in the MagicStay network of business travel-focused rental properties.
The deal will add to the 150,000 rental properties already on the MagicStay platform - a figure that has risen steadily since its launch in 2014.
OneFineStay currently has a total of 10,000 luxury properties.
The agreement comes almost two years on from OneFineStay's $160 million deal to sell to AccorHotels.
Since then the brand has seen the back of two CEOs (original boss Greg Marsh left shortly after the acquisition and Evan Frank left in the summer of 2017.
Deputy CEO Keyvan Nilforoushan also left in September last year.
Frank recently joined Context Travel as its new CEO.
France-based booking site MagicStay, which includes properties in city center locations or close to conference venues, has so raised €1.5 million from a group of angel investors.
