First of all, congratulations and best wishes for your continued good health! The hotel where we stayed was quintessentially Parisian & charming, IMO: Hotel des Grandes Ecoles in the Latin Quarter, about a 10-min walk from the Pantheon and about 15 min (without rushing) from the bridges to Ile St Louis and Ile de la Cite. It was recommended in the 2014 RS guide to France but I believe starting with 2015 the book eliminated this to focus on just a few neighborhoods in Paris.
It books up way ahead, so you may be too late to get a room for February, but here's the website. You could always try calling them in case they get a cancellation. https://www.hotel-grandes-ecoles.com/
The neighborhood has lots of casual restaurants and bistros, as well as at least one lovely traditional French sit-down restaurant, Le Volcan. http://restaurant-levolcan.fr/?lang=en
The bistro we liked was La Contrescarpe, located in the Place of the same name. http://hg2.com/venue/la-contrescarpe/
