hI!
I have not made up my mind as yet if I was going to take the trip at the end of September or the one in October.
I was in Paris last year by myself for a few days. I am French-Canadian with a Parisian accent, but I am fluent in both languages(French and English). I know a few good spots in Paris and I am familiar with the subway around the Champs-Élysées and St-Germain des Prés. A few spots that are very interesting are in the district called Le Marais, it is hip and very cultural, I would be interested in sharing information before the trip. I am a woman in her fifties but who behaves kind of very young for her age. Most of my friends are in their thirties, forties. I have friends who live outside Paris and would probably be interested in meeting with you and I. I might make up my mind and go in October, if you are interested in my proposition. I would not mind at all browse and go around Paris with you. Reply as soon as possible. I am taking a decision by the beginning of next week.
I have also been in Florence three years ago, and I know a couple of nice restaurants and a gelattaria which is the best I think.
