Great flat, very close to Schonbrunn (~ 5 min walk). Besides Schonbrunn there's another park where I spent my time with kids. Supermarket and bus stop is also close to appartment. It is easy to get to the Museums Quarter by 57A bus (don't forget to buy wochenkarte ticket in Tabak store or in Metro station). The closest shoppig street - Mariahilfer straße is easy to access by trams.
The flat itself is in good condition, I had everything I need - TV, WiFi, things for cooking, washing mashine etc.
Anna is a great host!
