I've known this hotel for 25 years and was delighted to find, returning after a gap, that I still love it! My room (108) was small but mostly mostly quiet and very comfortable.
Two suggestions: first, a power point or USB charging point near the bed would be useful nowadays; secondly, I think that in 2019 people are not so keen on drinking water in small, one-use plastic bottles. Maybe get stoppered glass bottles which can be filled daily with the famous local "eau de la municipalite"?
The restaurant is always reliable - though a little pricier than it used to be - and the breakfast buffet is good with quite a wide choice.
I understand the Bonnet family sold the hotel just ten days ago after many years' hands-on ownership: I hope standards and the unique style of the place will be maintained under the new regime.
I love this beautiful, lively town and the Saint Christophe, just steps from "La Rotonde", remains my hotel of choice. I shall return.
