The apartment is super nice, It made my stay in Vienna very comfortable and cozy. The place is very well situated (very close to the metro station and not far from the city center). The neighbourhood is cool as well, for example within just 2 minutes of walking you can find marvellous bakery with fresh and warm organic bred.
Spacious, with high ceilings and a lot of light in the morning- Heidi's place was better than I expected.
Would definitely love to come back!
