We loved our stay at Lionel 's apartment!
The location in the Marais is great, very central in Paris and close to lots of food shops, restaurants and subway station.
The apartment is charming indeed and very personally decorated.
(We loved the books.) The balcony with the plants is a great place to have breakfast with croissants in the morning.
Everything went well and although the dishwasher was out of order it was not so much of a problem since we ate out most of the time.
Lionel was easy to communicate with and arranged a very reliable person to get and return the keys. He made us feel very welcome with a bottle of Champagne! Too bad we did not have a chance to meet him.
We certainly would come back to his apartment.
