We had one of those at BRV about 2 years ago.
I wouldn't be confident there still are any there after the recent refurb.
The one we had in WL went away with the CC conversion, I'm pretty sure. I don't think the room we had even exists anymore.
That one didn't work at all. Maintenance attempted to fix it and was unsuccessful. We got a 1/2 night refund as a result.
The fact that those are such high maintenance probably resulted in most being replaced at first opportunity.
