Welcome to Thessoni classic - your seminar hotel with character, a place for people with ideas, visions and a desire for new perspectives.
Here, learning becomes a learning WORLD: our rooms have names like spinnerei, lernGARAGE or meisterWERK for a reason - they invite you to rethink the familiar and turn meetings into an experience.
Those who want to retreat will find cozy corners in the feuerLOUNGE to reflect, exchange ideas or simply pause for a moment.
Whether it's a creative conference, inspiring workshop, private party or large corporate event - here, content meets atmosphere, technology meets style, business meets pleasure.
Our versatile event areas can accommodate up to 300 guests - including state-of-the-art conference technology. And all framed by loving details: an antique rosewood secretary, hand-picked design pieces, copper pans on the ceilings - there is character in every corner.
And what would inspiration be without culinary delights?
Fresh market cuisine with show kitchen flair awaits you in the speiseKAMMER.
Steak and lobster fans will find their happiness in tonWERK - our 800° premium restaurant.
And at feinWERK by Himura, you can experience Japanese bar culture with sake, sushi & style.
Think creatively. Meet differently. Enjoy unforgettable moments.
That is Thessoni.

19.11.2019 - Boutiquehotel Thessoni classic, 8105 Regensdorf
Der Anlass hat völlig unseren Erwartungen entsprochen. Die Location ist etwas anderes und hat auch unseren Leuten enorm gefallen. Die Verpflegung und das Abendessen sind vielseitig und auf ausgezeichnetem Niveau. Der Ablauf lief reibungslos und für die knapp 100 Leute ergaben sich keine grösseren Verzögerungen. Der einzige Wermutstropfen ist, dass wir beim Essen auf zwei Seiten des Buffets Platz nehmen mussten. Vielen Dank für den tollen und unvergesslichen Anlass.
