I was visiting a friend nearby, and stay at the hotel, which is next to the Messe.
The hotel is easy to reach, next to the U3, which is a ring-metro goes around the major stations and the "hochbahn" which can view the harbour with this ride. The location is absolutely perfect in terms of public transport.
Hotel itself is a one-floor apartment in a residence-building, and has its own entrance, which is neither the entrance of 101 nor 103, so pay attention :)
The room was clean and tidy, I can see that they have some design with heart. coffee and fruits were available at the corridor and absolutely nice idea. It's just they don't have double bed, but they put twin bed together, which is not as I wish.
Overall this hotel is cool. and to be frank, I would recommend to anyone if it's 69-79EUR per night.
