Caroline was very helpful, supportive and flexible even as our arrival time delayed signifcantly.
All the communications needed ran smoothly and promptly.
The appartment is very nice and perfectly located for visits of Montmatre as well as for all other destination in Paris. You can reach the public transportation network (metro + bus) easily. Even a park house was not that far away which offered parking lots for a quite fair price.
We stayed there with four person (two adults + 2 children) and it was absolutely sufficient and comfortable.
