Real voices – What
event organizers say about us

For my birthday party I rented the basement room at the grand-hotel
rented. The grand-hotel team was super friendly and very helpful. The process was easy and uncomplicated! It was a great party! Thanks for that!

As an architecture firm, we celebrated our Christmas party with around 45 people at the Grandhotel Cosmopolis – a celebration that was a refreshing change from our previous events and which everyone was genuinely enthusiastic about.

What was particularly nice was the open, welcoming atmosphere: we were warmly welcomed, got exciting insights on a tour of the house and met many interesting people.

The organisation before and after the event was completely straightforward, the event space suited us perfectly and created a very pleasant atmosphere. The main courses were deliberately simple, yet very well prepared with great care and always served with a cheerful attitude. The desserts were varied and delicious. Thanks to a DJ on the small stage, there was even plenty of dancing at the end – an all-round successful evening that we all remember very fondly.
