I had a great time staying at Sofiane's place. Walking distance to the Sacre-Cœur, close to the métro and just steps away from cafés and brasseries. A word of warning, though: this place isn't for everyone. It's like a bohemian adventure. The place is tiny, the shared kitchen/bathroom is across the hall, you have to hike up to the septième étage (eighth floor to us Americans) and the street noise below never ceases. Imagine if Westworld added a Beat attraction, that's this place. Luckily, that's exactly what I was looking for.
