We stayed for 4 nights The apartment was lovely clean and cosy and so central.We walked everywhere and used the Hop on hop off Bus that was part of the Vienna Pass which we got for 3 days which was excellent value.
There were some lovely restaurants right next to the apartment especially loved the Italian restaurant just round the corner.
Hope to come back as did not have time to see places just outside Vienna.We took the taxi service arranged by Stefan which worked really well.Thanks again Stefan.
