The view from Christian's place is amazing. I lucked out as it was still available the week prior to my week-long trip to Paris. The location in Monmarte is unbeatable as it's 1 block away from Sacre Coeur. I'm a remote worker and wifi was strong the entire time. It's great for a solo traveler.
If views and location are a priority for you, this was a great find. Christian is very kind.
