Julia was a perfect host. It does not require many words: helpful but not intrusive, pleasant for a chat but who understand you need time for visit the city.
The room is like description, it's an old apartment but everything was clean. And you can decide the temperature you prefer.
Me and my girlfriend used the kitchen for 3 dinner in 4 days.
The location is just perfect in order to visit the city: 5 minites for U1 subway, 3 stops for Stephansplatz, 20 minutes by foot.
