We (me and my girlfriends) spent 3 days/2 nights in this wonderful apartment in Vienna. The location is perfect - only seconds away from the subway station "Stubentor" and a few minutes walk from Stephansplatz and all the surrounding sights. A grocery store (Spar), which is small but sufficient for everyday necessities, and the drugstore DM are around the corner. Also, there are many restaurants within walking distance.
The apartment itself is big and clean and has everything you could wish for. Although we were 5 girls, the apartment provided more than enough space for all of us. The beds were comfortable, the heating worked (which was important because it was quite cold outside) and bathroom and kitchen were well-equipped and clean.
Check-in and check-out was straightforward - Anna wasn't in Vienna the time we arrived and left, but we got the key from the cleaning lady and left it in the apartment when we departed. We could also check-in and check-out at times that were convenient for us.
Booking process was very easy because Anna replied all my mails within minutes and helped with all the questions I asked.
To put it briefly, everything was excellent and we would love to stay in that apartment again, whenever we come back to Vienna. Thank you for having us, Anna.
