This hotel is a big scam. The hotel owner was super rude and threatened us that she would have her employees pay for their fault. She did not, but instead charged extra on my card and provided false information when I filed a dispute. I suggest all guests to avoid this hotel at all cost. Don't risk the chance that they charge extra on your card. There are better hotels in Vienna and stayed there was one of my biggest regrets among all the international trips I've taken.
Prós: Receptionist was nice and friendly. There's fresh fruit infused water at the front desk and it was refreshing!
Contras: We were told that breakfast was included when we checked in, but upon departure, we were asked to pay for them. We refused because it's hotel's fault of giving us false information, and they agreed. They later charged us EXTRA when we returned home.
