This hotel has a veneer of elegance, but I was not impressed. The room was nice, the sheets and pillows were comfortable, and everything was clean, so it was by no means terrible.
But my room as absolutely freezing (and I normally prefer 68ºF rooms) and the thermostat was ancient and confusing (there were no numbers, just smiley face and the dial just kept turning with a red and blue light seemingly randomly lighting up separately and together). In addition, when I went to flush the toilet, the flush button fell off into the wall. Not wanting a plumber in my room all night, I made do, but that is annoying. Finally, I ordered room service and when I got the bill I found they had double billed me. In addition, they added a £1 donation on automatically with no notice on the menu or when I ordered. I absolutely hate when companies try and get me to donate for them. I donate to the causes I want, and they should do the same.
I stay in Belfast about every other week (at least in normal times) and will continue to prefer the Titanic, Grand Central, or Europa for when I am there.
