We had a lovely weekend in this airy and cute apartment.
It was really quiet since the apartment faces the inner courtyard, not the street. It's just as nice, if not better, than it looks from the photos and has all the basics you need.
There's a tube station less than 5min walk away and if you prefer walking around the city, then it's ca 20min to Naschmarkt and the old town.
I would definitely recommend it for someone who wants a a quiet stay near, but not directly in the city centre.
