We stayed here for 5 nights over Xmas and really enjoyed the flat. It has a great balcony, sadly it wasn't the weather for using it.

As for location it was convenient for arriving from the airport and getting around on Viennas excellent public transport.

Our hosts were genuinely lovely and helpful, with loads of useful suggestions which made the trip more enjoyable.

I can recommend Barbara & Geralds flat as a great base to explore Vienna.
