We were excellently accommodated by Wolfgang - we only booked the night before we arrived and were made to feel special from start to finish. We had a car and the previous guests were not leaving til later in the day so we met Wolfgang in the morning and dropped the car off at the apartment!
The apartement is exrememly well situated, around a 5 / 10 mins walk from all the main attractions of Vienna. The flat is in a quiet residential building which was perfect for us.
There was a welcome drink and 2 of the famous 'Mozart Balls' to try on our arrival. He also took time to recommend nice bars and things to do for our 1 day in Vienna.
We cannot recommend our hosts enough and the apartment is beautiful with everything you need!
