Like many have stated, this should NOT be rated as a 5 star for many resons.
First, the service - Very poor, slow and ignorant.
Second: The SPA is a disaster. It is more like a pool at Disney land. Loud kids with floating devices taking up the whole pool för hours. We had to leave as a child jumped from the side of the pool landing on us and it was impossible to have a conversation due to the level of noice. We assked the staff if there were any quiet hours, but they said "No this is the way it is on weekends and hollidays". No try to see it is very rare for a 5 star SPA to be a play area for children.
Third - The breakfast. Very limited and boring breakfast which consisted of cheese and bread for the most part, I have been to 3 star hotels that have had far better breakfast.
Late chekout is 50 EUR for 2 hrs, even though we has to stay because my son got a stress reaction after the SPA experience. No empathy from the "customer relations manager" he just was real quick asking me for a creditcard, even as I just had told him my son got hurt in the SPA.
Bottom line - This hotel is overrated. Do not stay there. Even Holiday Inn or any hotel is much better.
