Definelly recommended!
Our host Sandra was very helpfull and hospitable.
The apartment in historical building is in very quiet location, but only 5 minutes walk from U4 Margaretengürtel underground, very close to the city center and Schönbrunn. Overlooking to the garden. Fully equipped, also with washing mashine. A completely new bed with a very comfortable mattress. And you can watching fairy tales in TV from the bed in the morning :D
The whole apartment was perfectly clean.
We were very sad that we had to leave :(
