I went for a family trip to Paris from 9th July - 16th July. We were 5 people with 2 kids. Montmartre is a beautiful and safe borough with cinematic alleys.
The flat was on top of the hill, 600m away from the magnificent sacre coeur.
We loved the interior with all the details and elegant ornaments.
The best thing about the flat was of course the view from the kitchen window over Paris. It was breathtaking! As the 14th July is the national day of France, we really enjoyed the 30 min firework next to the Eiffel Tower from the kitchen window.
Karine was very nice and kind. She could speak english very well. The communication was organized and smooth.
I would totally recommend this flat to all wanderers and city lovers.
Keep in mind that the flat is on the 4th floor. A little exercise never killed nobody, though ;)
Also, prepare for extra fees for sheets and towels. After all you expect clean towels and sheets therefore it was bearable.
