The hotel was a very good choice - it is easy to reach with U1, and the hotel itself was clean, safe, and silent. The room was equipped with both Wlan and wired Internet, and the buffet breakfast was good.
In the blocks around the hotel there is not much to see, except the architecture of the surrounding buildings (the UNO City), but if you buy a 24- or 48-hour ticket to the public transportation it is relatively easy to reach the hotel and all the major attractions in Vienna city centre.
