The K K Palais Hotel, Vienna is situated in a quiet area of the city about 10 minutes from the centre. We felt very safe walking back there late in the evening and there was a local supermarket very close by, if needed.
The hotel was clean and offered a good selection of drinks at the bar and for the buffet breakfast, which was reasonably priced.
Our twin room was very clean and serviced daily with clean towels, complimentary water and tea/coffee etc. The room, on the 6th floor, was quiet and accessible by 2 reliable lifts and all communal areas were clean with a working cash machine in the lobby and computer access if needed.
Although we didn't have much contact with the front desk staff, except for checking in and out, we did ask for assistance getting a taxi and this was dealt with efficiently but time to destination and cost wasn't able to be got from the taxi firm for us.
Overall we had a pleasant stay and would consider staying here in the future.
Vienna is such a beautiful city :)
