About us

We’re celebrating our 25th anniversary. Join in the celebrations!

It all began 25 years ago with an idea and the courage to envision a new market. Today, Apartmentservice plays a pivotal role in shaping the serviced apartments sector across the German-speaking world. What began as Anett Gregorius’s thesis has grown into a company that sets standards, drives innovation and is regarded as a reliable partner for operators, investors and project developers. And it is precisely this story that we are celebrating – not just by looking back, but by bringing it to life. 

25 years. 25 doors. 25 special moments.

From 23 April to 1 June, a door will open here every day. Weekends and public holidays are excluded.

What’s in store for you?

  • Interviews with fascinating figures from the sector
  • Attractive accommodation vouchers for selected serviced apartments
  • An exclusive prize draw for the book *The Compendium of Apartment Concepts* by Anett Gregorius, Matthias Niemeyer and Henrik von Bothmer
  • A SO!APART Insight subscription


And above all:
Insights like never before. From 25 years of apartment services. Every door opens a new chapter. Telling the story of developments, of ideas – and of what has driven this industry. And perhaps also of what lies ahead.

Each door tells a little of this journey. And perhaps a little of the future too.

The grand finale on 1 June, our founding day, has a very special surprise in store:

We are giving away a ticket to SO!APART worth €1,950 plus VAT – the event, taking place on 18 and 19 November at the Metropol in Berlin, will be the highlight of our anniversary year.

One thing remains unchanged. We are looking ahead. Apartmentservice will continue to play an active role in shaping the evolution of flexible accommodation models and international mobility. With experience, conviction and the same dedication that started it all.

So it’s worth  staying tuned every day. Click here for the 25 doors.

Apartment Concepts are our world

Expert, pioneer, mastermind: We are exclusively specialised in apartment concepts. For over 20 years, our consulting work has been the basis for successful projects in the serviced apartment segment and new forms of living such as co-living. Through our agency platform apartmentservice.de we can directly track the success of our work. We recognise trends before statistics are available. Serviced apartments are our world because there is currently no real estate segment more exciting.

And because serviced apartments as part of the new world of apartment concepts are the answer to the mega trends of our time. Whether lifestyle-oriented concepts, mixed-use projects or large international serviced apartment brands - the rising star thinks bigger than ever before. Currently, the German market already has more than 44,000 serviced apartment units and by the end of 2025 at least 32 % will be added. What other branch can claimt that?

We are proud of our mile stones:
