The location is great, near Sacre-Coeur and 4 metro line station. Also really nice terrace in the apartment. And the owner of the flat was nice and responsive.
But we had a lot of stress when we arrived because cleaning lady forgot to put the key badge on the place where it was supposed to be. And the other stress in the evening same day because we saw 2 mice in the flat - one on the kitchen and another on the sofa, where one of us was supposed to sleep. So we were afraid of mice all the time there and we were hiding all our belongings into suitcases to prevent mice from gnawing it.
