Clean but decor sucks.
For a busy airport these toilets are kept immaculate. All the toilet paper was stocked up and decent hand wash facilities and dryers were supplied. They also supply toilet seat covers, which again is great to see.
The only real complaint was the overwelming decor choice (see pictures).
I like the way the toilet flush was located on the floor so you only have to use your foot to flush the toilet. Saves touching dirty toilet handles, a great idea, yet to be seen in UK.
