Location location location! Claus' apartment was unbeatable. Located in a quiet street, very close to Hofburg Palace, Albertina, Helmut Zilk-Platz, St Stephen's Cathedral, churches, museums and concert halls, it made traveling very convenient. Check in was easy and we were greeted by Bernard who showed us the amenities in the apartment. It was not very big, but enough for the four of us. The beds were comfortable but the pillows were way too soft for our liking. There was a washer which was great, but note that there's no dryer in case you need one. However there was a rack for us to hang the clothes after they were washed. There were many eating places around and we really loved the Italian restaurant just opposite to the apartment entrance. Had a great time in Vienna!
