Arte Luise Kunsthotel

At this 'gallery with rooms' each of the 50 units was designed by a different artist, who receive royalties whenever it’s rented. All sport high ceilings, oak floors and wonderfully imaginative, poetic or bizarre decor – we're especially fond of number 107 with its giant bed. For cash-strapped art fans there are smaller rooms with shared baths. Avoid those facing the train tracks. Breakfast €15.
