Overall its a really beautiful place to stay, I wasn't expecting it to be so nice apartment. Really big , high ceilings, recently renovated and comfy.
Now the bad ones : its not cheap, it'a not in the centre of Vienna , it was really dirty to places not easily seen like under the bed , they wouldn't offer a place to leave the luggage after the check out like most companies like these do.
To sum up , it's really great depsite the price but some improvements could be done
