Maureen and Sebastian are super nice. The location guide to the apartment provided by them are clear. We have no problems in finding the apartment. They also help us to keep our baggages aftern check out, which provided convenience to us.
The apartment is nice with great location, which is 5 mins walk to the main train station and underground station. It takes 3 stops from underground U1 to the central districts of vienna.
