I used to stay at Le Meridien Etoile a lot in 2017 because it was the cheapest SPG hotel in Paris and I needed nights to maintain Platinum.
I really don't like the location, it's too far west for me. A lot of airline staff used to stay there.
Elite recognition was pretty mediocre. Looking at the pictures the rooms don't look any different and aren't anything special. I would not recommend staying here, especially now that you have more options with Marriott
