I have been in Paris with my family, husband and two kids. It was a last minute decision in July and I was happy that I found a place at Airbnb.
Plus points: The building is very nice and very well located near the Sacré Coeur and extremely near the metro station. You will find supermarket nearby.
Negative experience: I have booked the apartment for 4, but when we arrived it was settled only for 2. We were received by Eli (since Nerea and Emilio weren’t there), a nice Spanish girl that tried her best to help us. There was not enough bed sheets and we had to cover one of my kids with our coats to sleep. I wrote Eli the days I stayed asking if she could send us more bed sheets, she told me that she was going to bring them, but this never happened! Eli washed the towel from the previous guest while we were there, in our arrival, but she settled the washing machine without centrifugation, so the towels was soaked with water and after a few minutes the apartment was like a river, and the water reached one of the mattress that was in the floor. I had to wash everything again with the right configuration and dry the floor! Cleaning was also not the best from the apartment, there was a lot of hair in the floor!
Since I´m a quite relaxed person those problems didn’t influence my stay in Paris!
