mermaid's cave

After a long day in Vienna, guests can sweat, cool off and relax – or the other way round – in the Mermaid’s Cave. Spanning 250sqm / 2691sqft, the spa area includes a tea and refreshments area and hanging chairs which rock gently, helping you to relax. Glass walls create oases of calm without hemming you in and allow you to admire the Berlin illustrator Olaf Hajek’s charming little mermaid from various angles.

meetings & events

The function suite with its outdoor terrace overlooking Weghuberpark provides the ideal backdrop for creative brainstorming and focussed discussions. Witty and original, the Freiraum function rooms can be rented individually or combined to cater for a range of events. All of the function rooms have modern, professional conference equipment. Organisers planning more unusual events can book exclusive use of the Wohnzimmer lounge and the Dachboden loft as well.
