We stayed here in March 2016 as it was the HQ Hotel for the Premier League Karate event in the town. Whilst we didn't take advantage of them as we were there for a specific purpose, the facilities looked great.
We went for a 3 hour pool experience with my children and I have to say that the pool was clean and cosy. There were quite a lot of people but it still felt not overcrowded. We found a spot for us in some minutes and enjoyed the experience. It is quite magical when the night comes, because of the huge glass roof. The prices are lower in the evening and there are less people.
I've stayed at this hotel a few times and I have to say that this is my favourite hotel in Slovenia. The rooms are very tidy and clean, the food is great, the swimming pools are awesome and the staff is friendly.
Room Tip: Rooms on the east side have a nice view of the river
Excellent Hotel with direct Access to the spa, clean and comfortable rooms, nice and friendly staff.
