Thomas H. Althoff has been instrumental in shaping the German hotel industry for more than 20 years, an industry that he first entered when he was little more than 20 years of age. He has become a truly recognised and very reliable personality to his companions and business partners, undoubtedly representing one of Germany’s key leaders in the hospitality industry.

Where we came from.

Thomas H. Althoff and his wife, Elke Diefenbach-Althoff, started the Cologne-based business known today as ALTHOFF HOTELS in 1984 with the Hotel Regent International, Cologne. Since then, the group has grown to a total of 15 hotels comprising 1,491 guest rooms in four countries. Identifying and passionately pursuing the right opportunities led to the group’s successful expansion based on a solid foundation. Driven by ambition and perfectionism, Thomas H. Althoff has created one of Europe’s finest luxury hotel brands – the ALTHOFF Hotel Collection – today comprising seven precious hotels in Germany, France and the United Kingdom. Building on this platform, he introduced the first class AMERON brand in 2009, currently with eight upscale business hotels in Germany and Switzerland. The takeover of the operation of the converted Schlosshotel Lerbach in 1992, previously owned by the von Siemens family, marked the entry into the luxury segment.

Eight years later, the group also assumed the management of the nearby Grandhotel Schloss Bensberg, which constitutes one of the most prestigious hotels in Germany, if not Europe. In light of the constant desire to further develop, the significant achievements to date and the solid financial performance over the years, it is only a natural consequence for Thomas H. Althoff to pursue expansion. “We aim to considerably increase our presence throughout Europe - however not at all cost. Each new property will be the result of a careful and sensible analysis, demonstrating that Althoff Hotels as the operator will add value for both the investor and the guest”. Longevity and reliability are important to Thomas H. Althoff, who pursues growth sensibly and feels a strong commitment both towards his guests and his business partners.

Cuisine, Architecture, Design & Service

The corporate philosophy of the Althoff Collection is based on a three-pillar concept that comprises the components culinary, architecture & design and service.

Thomas H. Althoff focuses on outstanding cuisine in each of his five-star hotels.

One of Thomas H. Althoff's hobbies is his preference for a sophisticated art collection and exceptional architecture combined with modern design. This mixture is characteristic for the hotels of the Althoff Collection.

Honest, unobtrusive service that creates a special atmosphere in the hotels of the Althoff Collection - this is the true secret of our success. We see ourselves as your host, who always responds personally to individual needs.

A World of many Worlds

The design of AMERON hotels is young and inspired by the region of each of its locations.

The cuisine is regional and particularly pleasurable, as it is oriented towards the ideas and expertise of the star kitchen of the Althoff Collection. For example, the Cantinetta restaurant concept is inspired by that of the Enoteca, and perfect service is just as important as outstanding cuisine at 15 Gault Millau points. 

Young, fresh and above all urban

Our new brand is young, fresh, stylish and above all urban. URBAN LOFT is aimed at business people, young people and families who value high quality standards and are looking for accommodation as if visiting friends far away from the anonymity of a foreign city. So we occupy our very own niche and design it individually, modern & unconventional.
