First off I have to say, I sometimes read bad reviews and say "oh that person was just having a bad day". I am not having a bad day and this is the first time I have to write a review that is not 5 stars and I will explain why.
-1 star for Cleanliness - Since Covid, apartments should be in a very clean, sterile if possible. When we arrived there were cobwebs every where, dirty spots on the floor, and dust and dirt behind tv stands, couches, and bookshelves. AirBnb was even involved and had to refund a portion of the fee with proof in photos and video
-1 Communication - Emmauel had good communication before and up to an incident in the apartment. While he does respond quickly, we had an incident in the apartment where the front door handle was broken. Upon closing the door the first evening, the handle did not work and we were locked inside. I messaged right away, and while the Messenger said "usually responds in 1 hour," we did not hear back from him until the next morning. We were lucky to mess around with the handle and get it open but could have been locked in for while. A worker did come and fix the handle the next day.
-1 For Safety - After the door was fixed, a lady came into the apartment while we were upstairs and startled us. I went downstairs to see what was happening and she said she was the cleaner and wanted to wash her hands. As stated by Emmanuel, no one would enter the apartment beyond the front reception, so this felt a little unsafe to us, had we not been there something could have gone wrong.
+1 Location - the location is great, close to a train station to get in an out of Vienna, about 10 minute walk to the Cathedrals and downtown with shops and restaurants
+1 Size - the two main bedrooms are large and fit 3 people easily, the living room is spacious enough to relax and spread out
Had we not had the mishaps the stay would have been 5 stars.
