Paris Hotels Topic and Hotels in Florence/Rome

300 euros per night is a very healthy budget. Your daughter-in-law should have no problem find a hotel that meets her needs. In case she or you do not know, September is peak season in Paris. My family goes to Paris 2 or 3 times per year and we do not rent apartments so we have been to a lot of hotels. Here is a list of well located places that I or members of my family have been to or stayed in over the years in Paris. These places are all charming and have IMO excellent staff and are well located and certainly quite clean. We don't stay in places that are not clean so here goes:

We have also like Artus Hotel and Hotel Atmosphere but IMO they are more modern and not heavy on Parisian charm (if by Parisian charm, she means less modern decor).

Excellent and very helpful info JHK. Thank you so much!
