We had have 3 days in Guillaume's beautiful appartement with a breathtaking view to Sacre Couer.
It is very close to the Metro station. Bars and restaurants are everywhere on the street. The small streets of Montmartre are around the corner und you can have a walk to Sacre Couer.
We did not met Guillaume personal but he organized everything perfect for us.
We defenetly would like to come back!
