Hello All,  I was planning on a slow travel itinerary, (now retired), as a start before possibly committing to something more permanent.  Solo male 67 yr. in very good health.  I was in France in '22 for a few weeks (Bayeux/Marseilles/Avignon/Paris) with some outside day trips in those areas.  I was thinking of doing three one-month stays (90 days total in the Schengen) but looking for ideas on a home base rental for this visit.  The idea would be to immerse locally and have some close by day trips in the surrounding areas.  I know the time of year will have some importance as to where/when I should be as well.  I would like to see different areas even though I loved the previous ones.  Some ideas below, off the top:
Brittany--St. Malo-Rennes-Dinan    ?
Cote d'Azur--Nice-Antibes-Marseilles  ?
Strasbourg?  Montpellier?  Bordeaux?  Lyon?  Paris?
I know I'm leaving out details of my interests, etc.  Looking for some starting point ideas.
