Adler Spa Thermae falsely advertises on its website and third party booking platforms that the rooms have air conditioning. Instead, the rooms are heated and cooled using irradiation panels in the floor and ceiling which were limited to increasing or decreasing the temperature by 3 degrees celsius from a 23 degree celsius starting point. It is an interesting concept, but the room did not cool quickly and I was too hot when going to bed. Luckily, the front desk provided a portable A/C unit, but it required us to keep our ground floor slider door open all night for the hose and vent to go outside. If I would have known that the rooms did not have air conditioning, I would have booked somewhere else as this is a mandatory requirement for me.
The spa does not have very good customer service. They sent an e-mail to me prior to my stay to ask if I wanted a personal consultation before my visit to go over the spa menu. I responded asking for one, but they never e-mailed or called me back. They encourage you to book spa treatments in advance, but then they have a an inflexible cancellation policy. One one of our days we decided in the morning around 10am that we didn't need our 5pm massages anymore, but they wouldn't allow us to cancel them and ended up charging the full amount to our room despite us not receiving any massage services.
