Thermen Soesterberg Tours and Activities

This hotel is simply amazing! The location is fantastic, and the staff are absolutely wonderful. The service is exceptional! The room is small, but honestly, we didn’t need anything more. The bed is incredibly comfortable, the room is completely soundproof and the blackout curtains make it perfectly dark, so we had a fantastic night’s sleep. We absolutely loved our stay and would definitely stay here again next time we visit. Highly recommended!

I've been staying at the Conservatorium regularly for 12 years now, and it is remarkably consistent: great location, awesome people, striking architecture, and the best gym of all the 5-star hotels in Amsterdam. This year, though, there was one welcome change and one not-so-great one: the breakfast has improved, with the addition of a buffet, which is convenient. But they also seem to have started letting local residents use the gym, so it's now super-packed at all hours, and you have to wait for machines. The gym has always been a big part of why I stayed there, so that's disappointing.
