The Serviced Apartment Co. will launch an online booking platform for corporate travel managers this month. MyCo will provide access to negotiated corporate rates, connect to the International SOS traveler tracking tool and feature in the Concur App Center. Once a traveler completes his or her stay, SACO can automatically send an e-receipt to Concur for expense reporting. SACO operates 800 apartments in the United Kingdom but will expand to 1,700 over the next two years, including in mainland Europe. A 77-apartment property, The Cannon, will open in London's financial district this month.
