Markus was very easy to communicate with and readily available to answer any questions upon arrival. The unit was clean, cozy and comfortable - everything we needed for our 4 nights in Vienna.
The bed was a little creaky but otherwise pretty comfortable. The shower head was a little low for my husband who is 6'2" but neither of these were really an inconvenience.
Overall check-in and out was a breeze and Markus attention to detail allowed for a wonderful stay!
