They just started offering free breakfast certificates for plats. I've also been upgraded 5/6 stays for a larger room, I think they classify it as a suite.

On 4/5 stays the room has been very clean. My last stay there was a large stain near the air conditioner (didn't bother me to much), but just wanted to disclose the only minor thing I noticed. On the + side the bedding is very clean and I've never had an issue with the rooms otherwise.
