There are photos of the room on their website, including some with the frosted glass bathroom. If you don't like the design of it, why book it and then make a fuss out of it? Also, I fail to see how this is a controversy. It's a design choice, some people like it, some people hate it.
“A design choice” 😂 I believe there was a famous episode of Homes under the Hammer where a previous owner had fitted a toilet on the upstairs landing because of space limitations. I should imagine he explained it was “a design choice” to anyone who saw it. You surely must be an architect or an interior designer? you sell it so sweetly. 😀 I also concur with others here that once I experience such “design choices” I make a “consumer choice” and take my business to a better establishment that allows me to sh*t on my own.
