My parents and I spent three nights in this hotel when we went to Wien. My parents slept in a double room and I in a single room, since it wasn't possible to have a three-bed room. We found this hotel very comfortable and we enjoyed it because it was close to the centre and in a quiet zone, near the Prater. The price was rather high, but we could afford it for such a short time.
interior is like other ibis hotels, neat, clean, warm. this one is situated near the riesenrad on the other bank of danube, it is not far from the center with the u-bahn, i woulndt recommend walk cos you get lost in one part of the crossing across the river. but that can also be done it is not too far for a walk. breakfast was great so be sure not to miss it. :) hotel is in one big avenue close to messe - vienna fair grounds. if u can choose, take the ibis on mariahilfer strasse but if that one is full this one is also good choice.
