Andrei gave extremely detailed instructions on how to arrive at and enter the apartment - I was impressed by his thoroughness and good communication.
The apartment is in a great location and is very colorful. While I found Vienna so walkable, it was a comfort to have a metro stop around the corner. I'll miss all of the charming cafés nearby but am sure I'll be revisiting Vienna in the not-too-distant future; I wouldn't hesitate to stay at any of his properties again.
