Aarhus has numerous smart chain hotels, mainly catering to business and conference crowds – these often have good weekend and summertime rates. If you’re after something special, book early at a boutique hotel or B&B.
The 'Where to Sleep' section of the VisitAarhus website (www.visitaarhus.com) lists rooms in private homes, plus private apartments for rent. Many are central and very well priced.
Note that where parking is offered, it's rarely free.
