Christoph’s place is very nice and cosy, more than enough space for three people. It has everything you need for you stay at Vienna. It’s located near Prater and near some good cafés and restaurants. Underground is nearby and we really enjoyed Prater Christmas market at this time of year. Christoph is really friendly and always responds quickly to your questions and messages. Unfortunately we couldn’t meet him in person but he kindly arranged for us to pick up the keys at the nearby restaurant. I highly recommend his place if you are visiting Vienna.
