We planned our honeymoon for Europe and Alice's place was a key part of it. Some of the best memories we had, regarding the places where we stayed, were there. The balcony is a prime place to start your morning, with a traditional Parisian breakfast (I recommend popping into the nearby bakery to get yourself some freshly baked baguettes or pain au chocolate). We enjoyed an espresso while overlooking rooftops and a dinner, while admiring the lit up Sacre Coeur.
The location is very good - you're close to the metro, there are bus lines and if you want, bikes, scooters and mopeds for rent, via apps.
Alice is very accommodating and a good communicator. She let us store a bags early before check in and never missed a beat to answer a message on the app. She's also got a solid decor for her apartment, which is btw loaded with kitchen supplies, a laundry machine and a firm bed (ideal for those who travel light and are staying a couple of days).
Would absolutely stay again.
