The facilities at this welness hotel are moderate. Not very many, but it's nit very busy either. The prices at the bar and restaurant are in my opinion very high for what you get.
What I noticed most is that all facilities are poorly maintained. If you start to pay attention you will notice everywhere things that are worn down, like carpets on the floors and stairs, tiles that are a bit loose and other frequently used elements to the point of breaking and tearing. Not expexted from a 4 star hotel. Beds for sleeping are ok, but don't expect a luxerious experience.
The service overall (exception aside) is minimal and not more friendly then absolutely necessary.
All in all it's ok for a night, but there are a lot better wellness hotels out there that are a better value for money.
