We had a wonderful stay at Wilson and Marielles place. It is located just steps away from the Sacre Coeur and a ten minute walk from the metro which will take you to all the sights. The Montmartre area itself is lovely with many cafes and restaurants. Just beware the many steps you will have to climb coming home each time. It was fine for us, and there is a funicular if you need it, but this may be a challenge for some, especially if you have a stroller. The place was bright and spacious. Wilson greeted us and showed us around with his charming daughters. He provided cold water in the fridge and coffee pods, as well as soap and shampoo. The kitchen worked well for us as we did make a few meals at home. Wilson gave us a list of recommended restaurants in the area and had maps and guidebooks available. They communicated very quickly and were friendly, thorough and clear in their communication. They answered any question we had and we had our best meal of the trip just a few doors down from their place. We came to Paris in the midst of a heat wave hitting the city where it was 35 degrees and we struggled to sleep without having AC or a fan. There are two windows which you can leave open but there are some mosquitos and not much breeze enters.
Overall, we recommend staying here. Wilson and Marielle were excellent hosts and we had a wonderful time in Paris.
