In Edge's "The Exploits & Triumphs in Europe of Paul Morphy", Dover 1973, p.
143 reads:

"Having again submitted our baggage to the inspections of numerous
officials, we (NB Edge & Morphy) thanked our stars for seeing the last of
the Chemin de Fer du Nord, - drove off to Meurice's, where they gave us
rooms about the fifteenth story, - started for the Restaurant des Trois
Freres Provencaux, ..."

Therefore I imagine that "Meurice's" was their residence in Paris.

Dear chess friends,

The year is 1858, the "annus mirabilis" of Paul Morphy. After the
Birmingham tournament, Morphy continued his correspondence with Staunton,
writing letters from Paris with a view to arranging the match, which, in
the
event, was frustrated. In the two letters dated 6th and 8th October,
Morphy
was writing from the Cafe de la Regence. Can anyone, please, tell me with
whom Morphy was staying in Paris?

Hope someone can oblige with this.

Best wishes,

John Townsend
