Supernice apartment - quite spacious, a lot of light, nice details, comfy couch (!) and veryvery clean. Everything necessary is provided (towels, bedsheets, even coffee). Very important for a girl - the apartment has a decent hairdryer! The only minor problem for me was that there is no window in the bedroom (a tiny one overlooking the corridor) but perfect for those who sleep better in the dark :). Metro and grocery store just a few minutes away, the city center 4 metro-stops away - so a very good but also quiet location.
Heidi was the perfect host - helped with all my questions, and was really quick to reply. Could not wish for a better first-time experience visiting Vienna and AirBnB!
