The apartment is clean and according to the pictures. Matthiue is a very helpful person and the contact with him is very clear. The apartment is in a super location with wonderful architecture and is very well connected to the rest of the city. The neighbourhood of the 18th arrondissement is an additional advantage as it is one of the most beautiful districts in Paris.
I highly recommend Matthieu's place as well as this location. Matthieu is a great guy and willing to help.
There were no unpleasant surprises and everything ran perfectly.
Good luck
