I had a wonderful time in Vienna. The appartment is located very conveniently only a 15 minute walk to the centre or 4 minutes to the metro station. It is clean with a lot of space and has everything you need for a great stay. I haven't met Kiki but picking up the key went perfect with the clear instructions and contact on forehand went smootly. I would recommend this appartment for anyone who would like to experience Vienna both long and short stay.
