This apartment is fantastic ! It is super centrally located and in a very trendy neighbourhood. You can reach all of the touristic spots by foot or conversely have a more authentic Parisian experience by having dinner or drink in one of the places on your doorstep.
We went as a group and the apartment was more than spacious for everyone. The kitchen and overall facilities are excellent. (Hot water, good wifi, TV, etc.)
Emmanuel and Constance are very responsive and excellent hosts !
I recommend their apartment as a great option that offers excellent value for your stay in Paris.
