The flat is pretty nice and comfortable and key handover with Bernadette was smooth. There could be more kitchen utensils, though. For instance we had no bread knife and the cutting board was in three pieces, no dish drying towels etc. Little other things could be improved, like for instance a hangers for hand towels and toilet rolls in the toilet. We also would have loved a freezer, but that is not available.
The size of the flat was quite okay for a family of four (kids aged 10 and 7). There was good space for putting our luggage in the bedroom.
But the best thing about the flat is the amazing location. It is a very lively area with all sorts of shops nearby. Plenty of dining and supermarket options in the area also. Goncourt metro station (line 11) is literally just outside the front door, and for access to more lines République and Bellevie stations are within easy walking distance.
All in all we highly recommend this flat. We some minor improvements it can be a really great option.
