Just a quick message having spoken to Thomas, the webmaster, who suggested this forum might be the right place!!
In brief, over the past few years I have worked on a website devoted to accommodation connected to famous figures from history. As it is, I've just added a new section which makes it even easier for visitors to find a place to stay linked to an individual they might be interested in, including Boswell (his entry is here http://www.nightsinthepast.com/historic-figures-b.html)
Anyway, I would be extremely interested to learn of any other places he might have stayed in addition to the couple that I've already listed. All information gratefully received!!
From 1777 to 1783 James Boswell was a columnist for the London Magazine, writing a total of seventy essays under the pseudonym the Hypochondriack.
