The apartment was a nice cosy place. Nicolas was friendly and very helpful. My partner and I never met him, but he left clear information and was available if we had any questions or issues—which we didn't.
I'd stay there again without hesitation.
One thing to note is that the bed, though very lovely to sleep in, is raised and requires using a built-in step. We were fine with it but it may be difficult for someone with mobility issues.
The local neighbourhood is very residential, which was fine for us. After a short walk we came across lots of cafés, bars, and restaurants.
The local metro station is 1 minute away by foot.
I would highly recommend this apartment.
