The building is with an amazing old aura while the apartment is freshly renovated. If you decide on living on Monmartre which is somewhat like living in a museum :), than this is an excellent choice. Flat is located on the upper floor but the stairs are ok and it's not a big burden. We stays there two adults and two kids, all felt very comfortable. Alexander welcomed us warmly and even helped to bring the luggage upstairs despite the heavy rain. We also appreciated his efforts to provide guidance on best eating and groceries options, it helped a lot. To sum it up - highly recommended.
