Had a great stay in this beautiful and very well equiped apartment. It has great connection on public transport to all the tourist attractions.(10 min)
Even though Diana was aboad, we communicated often through email. This was mostly due to a problem with wifi, which she was able to rectify promptly. She generously allowed us a little flexability with check in and out times.
Wouldn't stay anywhere else but here, if available, when I return to Vienna.
