The Hexagone building offers an outdoor pool and terrace accessible to all guests throughout their stay. You may access it by heading up to the 2nd floor and using your key fob to open the terrace doors.
The pool is only open for the summer season, and the dates may extend or reduce based on weather conditions.
Unfortunately, the Hexagone does not have any gym facilities, however there is a Klub Athletik just next door to the building that offers a variety of classes and fitness equipment. You may visit their website at http://www.klubathletik.com/ for further information.
