  • Accommodation in an Apartment with Balcony, with daily breakfast, for two
  • An upgrade to a Panorama Double Room on the 9th or 10th floor (subject to availability when booking) 
  • One hour in the panorama outdoor jacuzzi, with a bottle of sparkling wine and a fruit plate

  • Bath robe, slippers and towels (throughout the stay)
  • Free bus and train rides into the region of Konstanz

Why We Love It

  • The hotel has spectacular views over Lake Constance and the Alps
  • It's only five minutes' walk to the old town of Radolfzell
  • There's a solar-heated panoramic steam bath and whirlpool on the hotel's terrace
  • The hotel is within the world's first zero-energy skyscraper


The Designhotel aqua hotel is located in the south German town of Radolfzell on Lake Constance. The building combines sustainability with comfort and is described as "the world's first zero-energy skyscraper," by local newspaper Südkurier.

From the outside the hotel looks like an avant-garde spaceship, but inside the hotel offers warmth and comfort. The old tower shaft is made of bricks and the panoramic rooms are decorated with furniture made of local wood. The hotel has spectacular views over Lake Constance and the Alps.

We love the hot tub and the solar-heated panorama steam bath on the outdoor terrace on the eleventh floor. It's ten minutes' drive from Lake Constance and a five-minute walk into the old town or the city garden.

There's a breakfast buffet available in the Untersee Lounge. You can expect fresh, local produce, and we recommend that you try the bircher muesli.
