Very nice, clean and central place. The metro is just a few meters from the flat so you can travel to Stephansplatz (historic city centre) within 10min.
Directly at Märzstraße one of Vienna's most vibrant and ethnic shopping streets at district level - so you will find lots of good restaurants, bakeries, cafes, banks, a supermarket, a pharmacy and a tobacco shop within a blocks distance.
Definitely can recommend this place.
