My partner and I really enjoyed this apartment. We stayed here for a Romantic few days in Vienna and the location of this place proved fantastic for getting around. The tram and metro is just meters away, and you're in a great position to visit the Schönbrunn Palace just ten minutes away by tram, which I highly recommend. We had a picnic there and the tupperware provided in the kitchen was great for transporting the food.
The apartment might look far out on a map but the centre is just 15-20 mins away, and we found it very easy to go out in the day, come back briefly to change, and then go out for the evening again. The metro seems to run quite late too.
The space is clean, bright, and has everything you need.
Berndt was also excellent with my questions for local tips and restaurant suggestions.
Overall, a fantastic place.
