First of all, we had a great time at Vienna, but I had some issues with the apartment. CheckVienna forgets to say that they have room categories, and what you get is not what is shown on the pictures. When you book a room with a double bed, and XY equipment, you will get a similiar apartment with the same equipment, but not the same one.
The apartment on the pictures look comfy, a place where you can feel at home. However, what we got is just an ugly place, that TECHNICALLY had all the equipment that were listed on the page, but it was just ugly. I felt dirty while staying in this place.
The walls were filthy with full of handprints, chair marks, dead bugs, broken edges, missing plaster, and so on. It looked like it was constantly used for 4-5 years without a maintenance painting or anything like that... In the bathroom the knob of the shower and the lever of the toliet were broken, and the security lock on the front door were broken off. It was just not what I booked. I know that nobody will make new pictures after every month of their apartment, but this attrition was just too much.
I feel like that not mentioning that you have categories, and what you book is not what you get, is a rip off. If I knew this place looked like this, I would have booked another place. (Yeah, it had everything that was on the listing, but the ugly walls, doors, and so on is enough for me to make me feel dirty being in this place)
And by the way, two single bed is not equal with a double bed. We got two single bed size blanket which is not nearly as comfy as a double bed sized one for couples.
For these reasons I cannot recommend any places from CheckVienna, but I see that many of the reviews are positive, so I guess we were unlucky to get this ugly apartment. Roll your dice when you make a reservation!
