We stayed at the Paris flat for 6nights and the overall stay was very pleasant. The apartment is smaller than it seemed, but it was still big enough for four of us. The apartment seemed newly renovated. One bad thing was that it was located on the french fourth floor without an elevator, and it was hard to carry all the luggages up and down (cuz we had a lot). During the stay, the wifi suddenly got shut off, but the host kindly helped us out to solve the problem, and had no problem with the wifi after that.
The location was great. All the famous attractions were close by, and Rue Montorgueil which is located right next to the apartment has lots of good restaurants, cafes, patisseries and boulangeries. We had baguette every morning from Eric Kayser. A real french baguette was nothing like what I had before.
