Florian was away at our time of stay, but he arrranged for one of his lovely friends to met us. Katrin was very helpful and told us of loads of nice places to eat and go. Florian beforehand gave us lots of information and was quick to respond to any messages. Appartment was well equipped and had everything we needed. The apartment is roughly a 20 minute walk from the centre of Vienna but there was close tram links and meant that the area was quieter. Would definitely recommend this place to anyone wanting to visit Vienna.
