Stayed here in December for a few nights.
Staff was very friendly and recognized my Bonvoy status with an upgrade to a junior suite with a balcony. The junior suite was slightly on the tired side, but maintained well enough.
Post-stay, received correct amount of points and night credits within a couple of days.
In terms of branding, all my email communications were from the Le Meridien brand and chatting with the hotel staff - they confirmed that this will be the brand once the rebranding process is done.
