We spent a month in this apartment and it was very pleasant time!
The Apartment is brand new, very clean with good design. The kitchen is fully equipped, include an ofen and a coffee machine.
In Bathroom there is a washer machine with drying function, which was very helpful.
The area also pretty nice. 20-30 min. to Schonbrunn by foot, 5 min. to subway station Johnstrasse and 20-30 min. to the heart of the city - Stephan Platz. There are also a tiny Bakeries with turkish sweets and several supermarkets nearby.
I totally recommend this Apartment for short and long staying. Uschi and Benjamin are really nice hosts, we didn't get any problem. Even more, they always ready to help their guests.
