About us

What happened until now:

Countless international business trips and overnight stays in hotels that claim to offer their customers a "home" even though they are far from home. One thing came into Raphaels mind at this time: No hotel around the world can replace his home. Not even a little.
But... It doesn’t even have to!

What are the demands of travelers? Does a private holidaymaker need the same services as someone who is on the road? The answers are in Raphaels business plan.

The first apartments named "Sky Residence" are opened in Graz.

There are already 9 apartments. Guests like taking advantage of the unique services. And the freedom that an apartment offers - compared to a hotel. Therefore, the next apartments in Vienna follow.

There are already 15 Business Apartments of Sky Residence in Graz and Vienna. The current bookings show, however, that not only business travelers book, but increasingly also private holidaymakers. The concept will be further expanded.

The proximity to the AKH in Vienna can also be used. More and more long-term patients book at Sky Residence.

The Sky Residence brand needs an upgrade. The new, different target groups no longer fit into the "Business Apartments" drawer. In November, RK Apartments GmbH will be renamed Sky Residence GmbH. Premium Apartments are selected from Business Apartments. Raphael is flexible. The design adapts to the guests - as does the services offered by Rafael Kaiser Premium Apartments. Rafael Kaiser stands symbolically for the youthfulness of the CEO in combination with the excellent service you expect in Austria - you can feel like a „Kaiser“, German word for emperor!
