Markus place is in a nice neighborhood, only one block away from public transport and the beautiful Augarten park.
He provided me with a bike that I used on my trips downtown (10min)... The apartment is so big and nice, it´s completly new renovated and has a terrafic patio. Everything was well organized, check-in and communication was smooth and easy!
Next time I return to Vienna I will defintely stay there again... And the bed was super comfortable too, not too soft, just perfect!
