Do not hesitate to book that place! The location is ideal : grocery nearby, 2 metro lines for shonbrunn and city center (even though city centre is totally walkable), a cute brunch place just below, very quiet, air con for hot summer time, good wifi, kitchen well-equipped (even the dishwasher tablets were there) and Thomas is very accommodating (we arrived by midnight!!) and full of good advice to visit the city.
