Really professional and courteous hosts that couldn't do enough to help us when we had a problem.
Great space in Vienna, not too far from the centre with public transport (20 mins ish). Just be aware the Vienna public transport system is very confusing!!
Little kitchen area with hob for preparing small basic meals, breakfast, making coffee etc, and there is a supermarket just round the corner which is very useful.
Free WiFi (which works really well unlike some) and a comfy bed.
We really enjoyed our stay!
