The Rezidor Hotel Group (RHG) has announced plans to launch a new 305-room Radisson Blu property to guests in Istanbul, Turkey, during the third quarter of 2012.

Istanbul Sisli is the fourth Radisson Blu-operated hotel to be developed in the city and is set to feature a spa and an outdoor swimming pool, along with two restaurants and a ballroom.

Meeting space totalling around 2,000sq m (21,528sq ft) will also form part of the Dilek Holding-owned property, which will take Radisson Blu to nearly 1,000 rooms in Istanbul.

RHG president and chief executive officer Kurt Ritter said: "This business and leisure hotel is our 4th property in operation and under development in greater Istanbul and brings our total number of rooms to almost 1,000.

"This clearly underlines how strategically important the Istanbul market is for our company."

It will join the Radisson Blu Bosphorus Hotel; the Radisson Blu Conference and Airport Hotel; and the Radisson Blu Hotel, Istanbul Asia - the latter of which is currently being developed.
