25hours hotel number one

sit down and wait for superman.

The Freiraum concept is about providing unusual venues and relaxed alternatives to grey, run-of-the-mill conferences. It caters for all occasions: classic conferences and meetings as well as incentives, product presentations and even parties or exhibitions.


Break out of the daily grind with the two flexible Freiraum function rooms at the 25hours Hotel Hamburg Number One and try something different. This is a great place for creative minds to find fresh inspiration and successfully wrap up projects. If you need a little more room and a more laid-back atmosphere, the Wohnzimmer lounge and Freiraum 1 can be combined to create the Freiraum XL with a total area of 170sqm / 1830sqft and space for 150 guests.

living room with event bar

Whether you’re organising an after-work party, a birthday celebration, an informal get-together or a large-scale reception, the Wohnzimmer lounge and Eventbar are a great venue for everything from incentives and conferences to leisure events. If you need more space, the room dividers can simply be pushed back to integrate the Freiraum 1.

The chefs at the Esszimmer restaurant are always happy to cook up a storm, whatever the occasion. At lunchtime or in the evening following a successful meeting, diners can eat together at a communal table. The informal atmosphere makes this a great place for colleagues to become friends and delegates to become acquaintances.

rooftop terrace

The rooftop terrace provides plenty of space to arrange your thoughts and recharge your batteries during or after heated debates. With a little help from the Esszimmer team, it is also the perfect place for a barbecue with colleagues or friends.
