I stayed there in Oct. 2023. Here is what I had to say about it at the time:
I stayed at the Hotel Lion d’Or. This hotel was not great. The RS book describes it as having “pleasingly posh décor” and that may have been the case 20 years ago, but it just felt dated to me. I wondered how long the decorative green blanket at the end of the bed had been there. And the carpet had seen better days. I picked it for the location near the train station because I would be taking day trips. My room faced the train station and it was very loud, even with the window closed. Loud from people, not the trains. This was a train station that people liked to hang out in front of and there were often police officers there dealing with people. I think trying to get them to move on.

It’s current rating on Booking.com is 8.5. So, not terrible.
I probably wouldn't stay there again. But it was clean and the staff was friendly. It was convenient to the train station for my day trips. If you have other options, i would look elsewhere. If your options are limited, it wasn't a terrible hotel, just not one of my favorites.
