Space is a significant cost driver, especially in popular metropolises, and staff is another. Hotel chains such as Formule 1, which belongs to the Accor Group, count on tiny rooms without their own sanitary facilities and the simplest buildings on the outskirts and access via pin code. The modern representatives like the Buddy in Munich do without a classical reception, but they put coffee machines in the room, if you have any questions you can send them via tablet. "These hotels have an audience that has certain requirements, but which can be met in the smallest of spaces," says Dietl.
