This apartment is a great place to rent solo or as a couple. It's clean, very comfortable and has all the necessities you need (even a tiny dishwasher and washer + heating drying rack). The place is super cozy with lots of personal art decorations and tons of books. It's well located, about a 15 minute walk to the Sacre-Coeur, and has tons of bistros and grocery stores around.
There are a few metro stops about 5-10 min walk away, so very convenient if you want to visit other neighborhoods.
If you are working remotely, it's also very convenient. There is a desk and the Internet connection is stable.
I highly recommend staying at this place, it makes you want to move to Paris!
