I can only give stars for the hotel’s location; everything else deserves zero stars.
The staff was not helpful, and the internet service was terrible. For a five-star hotel, the Wi-Fi reminded me of a dial-up connection from 30 years ago.
We booked a room for three people, but the third bed provided was essentially a small fold-out cot that was extremely uncomfortable. The hotel was unable to offer a proper bed or move us to a larger room. As a result, we had to book an additional room for our son. In reality, we ended up paying for a room advertised for three guests and then an extra room for two more guests.
The hotel staff made little effort to resolve the situation, which was very disappointing.
Vienna is one of the most beautiful cities in the world, and we will definitely return in the future but we will not be staying at this hotel again.
