Nicely decorated flat with a very well-equipped kitchen and a comfortable bed. Belleville has a great atmosphere and offers many good restaurants and bars and Iris gave me some great tips on where to go. Metro lines 2 and 11 are just around the corner, so you can easily get to the city center and Montmartre.
The street can be a bit noisy on market days, but that didn't bother us.
All in all, we had a great stay. Thank you for having us!
