We spent 4 nights in Charles' wonderful flat in Montmartre - this was our first AirBnB experience, and it was a very good one! Charles was really nice and easygoing, and came to meet us in a cafe nearby from where we went to the flat; the place is in a great location, two Metro stations are very close by.
Everything in the flat was in order, and Charles had even drawn up a map for us with recommended places to eat/drink nearby. We went to have our first brunch in Paris in one of those bar/cafés, and it was indeed a great place. Good recommendations from Charles.
All in all we had a great experience in Paris and staying in Charles' charming flat - we would definitely stay there again and would recommend to friends!
