We stayed at Matthieu's for three months after moving to Paris and it was a wonderful experience. He was quick to respond to any questions and gave a warm welcome to our timide poodle. The apartment is gorgeous- clean, bright, comfy, everything just as presented in photos. The neighborhood is close to the tourist attractions towards Montmarte but also offers many trendy bars and restos on the quieter streets below Rue Clichy. Would definitely recommend his place to anyone looking to stay in the 9th.
