Our stayed at Charles place was very good, the apartment was nice and location perfect!
Charles was available when needed, somethings you really appreciate when abroad.
Into the heart of Monmarte, you can walk everywhere, many shops are right on the street , perfect when you go back at home after a day spent out.
We felt like parisienne living the everyday life, Paris is amazing and even better when you have a very good accomodation.
I strongly recommend Charles 's place for an authentic experience.
