I've just found a delightful book. I bought a second hand copy in perfect condition from Oxfam, through Amazon. It's an attractive small volume complete with box.
It is Artists in Residence by Dana Micucci - a guide to the homes and studios of eight 19C artists in and around Paris, including how to get there, where to stay and where to eat, and already has me dreaming of some wonderful trips to Paris to see them. (Out of date, but updating online shouldn't be too hard.)
I do seem to have got the travel bug back after a number of years of not being particularly interested in leaving home. I suspect it has something to do with 'filling the well' again after some intensive painting.
And this sounds like just the thing....
