Great hotel and different to the normal chain hotels I stay in. Check in is a little odd in that it's only manned for a few hours, so it might be awkward if your arriving late. The room was big and well appointed, although a desk to be able to do some work would have been great. The bathroom was spacious with a big bath and walk in shower.
The slight negatives with the facilities :
The room was really warm with no Air Conditioning, and as the room was on the ground floor, I could really open the window very much as people could look right in to the room.
Breakfast was a real positive, friendly service and the food was freshly cooked to order. I stay in a lot of hotels in Cardiff and I can honestly say this is the best breakfast I have had.
Overall a great hotel in a perfect Cardiff Bay location.
