This is a large flat, with generously sized rooms and was clean and well presented. The location is convenient - 1-minute walk to Charonnes metro station, a supermarket across the road, a street market, and lots of bars and restaurants really close by. The couple of neighbours we met were friendly too.
It's worth noting that the access to the flat is a door between two takeaways, which you then follow down a passageway and yard before another locked door to the stairwell. We arrived late due to travel delays and in the dark it felt a bit intimidating.
We also had a couple of issues during our stay - the bathroom leaking into the flat underneath, and the sofa being broken. Overall the apartment met our needs and we had a good stay.
