It is located in the Duitse Huis complex of buildings, including part of the old monastery of the Bailiwick of Utrecht of the Teutonic Knights founded in 1348.

Most of the rooms and suites are in a former military hospital, which dates from 1823 and has been carefully renovated, or in the modern Roman wing opened in 2008.

The hotel contains a Roman-themed health center, conference rooms, a bar, brasserie and the Grand Restaurant Karel V. It is set in extensive grounds.

[1] In the sixteenth century, Charles the Fifth (Karl V), who was emperor of the German Empire, king of Spain and sovereign ruler of the seventeen Netherlands' provinces, stayed at this monastery which by then also served as a hospital.

Napoleon's brother Louis Bonaparte bought the property in 1807 and the Teutonic Order left the premises.

[3] In 1995 the Bailiwick of Utrecht moved back into the 15th century Commander's house on the corner of Springweg and Walsteeg.

[7] Traces of the past history of the complex, including objects, photographs and historical drawings, are displayed throughout the hotel.

[11] The chapter room and refectory of the main building of the medieval Duitse Huis are now also dining areas.

[12] The remains of a fireplace were found during the renovation on which the double-headed eagle, the emblem of Charles V, was engraved in sandstone.
