My boyfriend and I were very happy with the flat. Everything was exactly as described and shown on the Airbnb website, and we received detailed instructions in advance that we followed with no problems at all. Kevin checked in on us during our stay, but everything was fine and we didn't need any assistance.
The flat is just off Boulevard Saint-Germain and a very short walk to grocery stores and the Seine. It's easy to get to the flat by metro and then it's well-located to walk nearly anywhere in central Paris. The flat is on a charming street with a butcher, fishmonger, patisserie, and other shops that we enjoyed.
