There was a glitch with the app and Michael didn't receive 6 of our messages.
We were greeted by a gentleman who spoke little English. We missed a few things (coffee maker, toaster, a bread knife, a cutting board) and the dishwasher didn't work. I also wish we had a reading lamp.
Otherwise, the apartment is centrally located, very close to St. Stephen. It is recently renovated and quite convenient. Besides, the price is unbeatable.
We enjoyed our stay in Vienna very much.
