Looks exactly as on photos. Checkin process is convenient, you can check in at anytime, Andrei sends details instructions (probably TOO DETAILED). Check in process looks quite like a quest :)
An apartment is a part of Andrei's office and there are some other apartments there. So you can hear some other people. In addition, an apartment is placed on the first floor and you can hear some people walking by the street. It's better to close the window for the night.
There's a wonderful bakery down the street, on the crossing of Esterhazygasse and Gumperdorfer Straße.
Andrei is a nice and communicative guy.
