The apartment is right next to the Naschmarkt where you have loads of options for restaurants, bars, and shopping. It is in 20minuts walking distance from the St.Stephan Cathedral and the city center.
We were staying for 2 nights and it was big enough for 2 people.
Though what would be good to know is that the big windows are facing the street and if you don’t close the curtains everyone is able to look inside the apartment.
Also you can hear the cars and people talking outside the apartment (we didn’t mind that tough, since we were out a lot).
Christian responds very fast for any requests/ questions.
