We stayed at Guillaume's place for two nights. The apartment is very compact with a spacious bathroom and kitchen. The room is enough for two people, and has a terrace with a beautiful view of Montmartre. It is clean and quiet, so you can rest without any problems. The environment where the apartment is located is quiet, close to the streets with many restaurants and shops. The metro station which is connected to all important locations is very close. Guillaume was excellent even before our arrival in Paris. He explained in detail how we can get to his apartment from the airport, how long it will take us, and how much it will cost us. He was very pleasant and friendly during the stay. I would recommend this accommodation to everyone.
