I went for a business trip with my father, room was ok, only we asked 2 single beds in place of one double, and they were sticked like one double (so there was few difference).
We stayed 2 nights and I could enjoy the wellness area, it was well disposed and complete (hidromassage sauna, tanning bed, rest room, steambath), full of towels and most of all very clean, only I prefer a warmer water during hidromassage, but this is my preference.
Restaurant was very good quality, only there were bit long waitings and few choiches, but I'm Italian and we are used to many choices of first dishes, then second and side dishes, then fruits and desserts.
Also hotel is very well served with bus, it stops in front of the hotel, and in 15 min you can reach the new Messe Fair, we went also in City centre (Marienplatz) and it is quite fast to reach (about 30 min.).
Overall I have to say it was a good stay and I'll probably return here for my next visit in this city.
