We did not met with Timur in peron, but the communication was great and quick.
He sent us very detailed guidance about not just the apartment but Vienna. What to see, where to eat, how to travel, even about the lockery at the main train station which was a very good suggestion.
Check-in and check-out is the smoothest. You can find the key at the entrance lock, and you should put it there when left. No need to wait for anyone, which sometimes can be troublesome for all parties. Don't know why this is not so common - yet.
The apartment is the one what you can see on the picture, however the bathroom is a bit small, and there is no hanger for the towel(s). Also seems to be a bit "self-reconstructed".
On the other hand the room is huge, as well as the cabinet and the bed. The bed is the best. :) King size. The heating is also very simple, it is by electrical wall, quick.
Last but not least, it is not so common and for those who travel e.g. by Wizzair or something similar, and there is no extra luggage, you will find salt, sugar, tea!, coffee!, showergel, conditioner!. This is a huge pro I think.
