The friendly, fully-equipped appartment overlooking an inside garden (not the street) is 2 minutes from public transport (U3) and about 10 minutes from the city center (Stephansdom). Tip: use qando app, not google maps to check distances.
A shopping street (Landstrasser Hauptstrasse) is also 2 minutes away on foot. Despite construction work next door, no noise got inside the appartment.
The host responded very fast, was extremely friendly and attentive throughout my stay and fully respected my privacy. I also found a surprise welcome present on arrival.
