My client got us #402 at Pasha the other day.
The room has a relatively big bath tab and a mat on the side.
I think #202, 302 and 502 have the same layout, too.
I have had #503 and #303 also quite recently. Both rooms have a mat but the size of bath tab is not so big.
I went to Perrier a couple years ago and the room had a nice spacious bathroom and mat. Went back again later and the next room didn't have it, which was quite a disappointment. Get the best room there if you can!
