„We very much look forward to this merger, as we can combine our individual expertise, thus offering our clients in the DACH-region a seamless portfolio of highly professional services under one roof“, say the partners.


Our services focus one hundred percent at optimizing the real estate value of hotels

Our clients choose us because we have earned a reputation for impartial, expert advice that will often mean the difference between success and failure.

You plan a new hotel and need impartial advice on the suitability of the location?
