Wonderful welcome from Dietmar : he waited for us late in the evening whereas our flight was late!
Very responsive via WhatsApp : the best host you can imagine.
The appartement is fully equipped and sparkling clean.
Don't be afraid by the location and the need to take public transports, we have used them for four days and never had to wait longer than 5minutes.
I would strongly my friends who come to Wien to be the lucky hosts of Dietmar and Christa.
