Things were mostly very good but there were a few downsides.
The good:
The room was dark and quiet for sleeping (and, despite our room being next to the lift, that was quiet); the desk was useful, bed lights and tables were good, the bath was really nice and the shower cubicle had a lip so the water didn't leak into the bathroom. The staff were friendly and helpful.
The not so good:
There were no accessible power sockets next to the bed so I needed to use my extension lead for my CPAP machine; the USB sockets were behind the TV, which made them awkward to get at; the bed was a bit hard and we could feel each other move. The taps were somewhat design over function - the shower taps were one above the other and didn't have any markings on them (for reference, the hot was at the top). Similarly, the cupboard/drawer handles were very awkward to use.
While it was nice to have a balcony, it had no furniture. The roof "garden" is accessible but its bar isn't open and there is no cover.
