The Rezidor Hotel Group has gone into partnership with Thalassa Hotels to relaunch the Tunisian group's Monastir property as the Radisson Blu Resort & Thalasso, Monastir.
The 280 room-property will be re-branded as of November 2009.
The most notable revamp will see two spas added: Cinq Mondes and Thal'ion Thalasso, measuring 14,000sqm between them and featuring pools, saunas, hammams and treatment rooms.
Some 20 spa suites measuring 70 to 250sqm will also be available.
"We are very pleased to add this hotel to our growing resort portfolio", said Rezidor president Kurt Ritter. "The property benefits from an excellent location on a five hectare beachfront site and is both a leisure and business destination of highest quality."
