We spent a few nights at Philipp's place whilst on a short break in Vienna. The flat is light and airy, with high ceilings, and is in a characterful apartment block with an "authentic" Viennese feel. It is very convenient for the U-Bahn and is therefore only a short trip from the city centre. The bed is very comfortable and we slept well! Communication from Philipp and his friend was quick and responsive to our slight change in arrival time. Overall, this is a comfortable and well-located flat, and we had an enjoyable stay.
