Is there a reception desk?

Where can I park?
We don't have our own parking, but there are alternatives close by. The Hallenbad car park or the Stadttheater parking garage, both within walking distance. From 6:00 PM, parking in the surrounding area is free. You'll find more details in our blog: Parking on Donaustraße and the surrounding area
What's the difference between the room categories?
All rooms come with designer furniture and a fully equipped kitchen - the difference lies in size and layout: Single rooms for 1 person, studios for 2+ people (25-43 sqm) for more space, suites (30 sqm) with a separate living and sleeping area, and apartments (80-120 sqm) for up to 6 people.
Is the kitchen fully equipped?
Yes - induction hob, oven, microwave, fridge, dishes, all from Bosch. Most apartments also have a dishwasher.
Mission Statement
