My husband, myself and our son stayed in Guillaume's apartment in Paris travelling in Europe for vacation time. This was a fantastic stay. The apartment is gorgeous like on the pictures, very clean and with all the confort including dishwaher and washing-machine. The real plus I have to say is the beautiful terrasse and garden where you can relax after a day of visit ! Guillaume is a great host. He welcomes us and show us how everything was working in his apartment. He was available to answer questions and also to make suggestions.
The apartment is very centrally located in a nice and safe neighbourhood which was important for our child. We could go to bakery and restaurants right outside the apartment and could go to museums and monuments (centre George Pompidou, Jewish museum, Notre Dame etc...) by foot. This apartment is really a gem in the center of Paris. I can't recommend it more. I will definitely come back with family there.
