Very nice location and apartment.
Don’t be scared because it is in the cellar! The passage to the apartment could be a little tidier, but once you get inside is fine.
The apartment looks better in the pictures, they were taken professionaly i guess, but i have nothing to complain about; the apartment looks good and is is a good condition overall. Despite missing large windows is quite bright inside during the day.
We went in December, it was warm enough inside, nothing to complain.
The location is awesome! Very well connected to public transport. If you arrive by car parking is a little difficult in the area, but i recomment to leave your car at Parking Garage P+R Erdberg. Cheap parking and well connected to the same public transport.
In the area of the apartment did not check other than the Belvedere Castle, but is a nice, calm area. Felt safe diring the day but also at night.
I recommend the stay!
@Tom: one suggestion if i may, i would provide 2 sets of keys.
Until next time!
