The apartment is very clean, tidy and cozy .. we felt sad leaving it. Dennis was very helpful, he let us check out hours later than what is stayed and he was especially helpful and kindhearted during new year's Eve, we lost the apartment keys, I have contacted him, and he was quick to respond and left his girlfriend and arrangements 3:00 in the morning to aid us. Highly recommended and if would go back to Vienna I will definitely stay there again.
