This apartment is so useful for buying foods to cook and transportation to go to any places in Paris.
And hosts responded to guests so early. If you book here, you can be easy to come to Paris without any questions.
I recommend to stay here two people.
You can use places to sleep confortable.
And it is a little hard to carry your baggage on 4th floor without elevator(I think almost apartment in Paris you cannot use elevator, so it is not only matter of this appartement.)
From this apartment you can go to Basilique du Sacré-Cœur and Dali museum easily.
At night you can see great view and live performances from front of Basilique du Sacré-Cœur.
Hope your trip is getting better with this apartment:)
