thank you for your kind question.
I our hotel we have only indoor pool in the Spa area with sauna and steam room.
For any further questions please do not hesitate to contact us.
No, it has an indoor pool only with an outside enclosed terrace area. In the summer the doors are left open between the pool and terrace, so it's almost like having an outdoor pool. However there is also a half-olympic outdoor pool just a few minutes walk at MOM Sport which is very reasonably priced.
Hope that helps.
