We had good communication with the host. We mentioned we were arriving to Vienna by train, and He provided directions via the U-Bahn to his place. The apartment is just a few short minutes from the subway. The subway station was just a short ride to almost everything in Vienna.
The apartment was large, clean, and comfortable with a million dollar view of the city.
Check in and out was done with the apartment concierge. A quick and friendly process.
We did not find any negatives with our stay.
Would highly recommend this place.
