We have stayed in airbnb's in 14 different countries around the world now and have met all different kinds of hosts and have good reviews from them.
Our experience is that Maximillien is easiest to contact by directly calling him instead of the usual airbnb messaging app.
Once we were able to contact him, he confirmed our stay and was kind enough to allow us early check in on our arrival date.
He met us personally to give us the keys and orient us to the apartment. he was a nice guy to meet in person. he explained that he himself would be leaving for holiday as well during our stay.
His place is in a great location, with a enough space for our family of 5. it is comfortable and complete. the washing machine was great. it is on the 1st floor (1 floor up from ground floor in case you have a very very heavy suitcase) with a great view of the bustling, lively street. some of Max's personal things are in the apartment but when guests are around he gives them total solitary access to the space.
we have some suggestions on improving the stay and the apartment itself and we have private messaged him to inform him about these. overall however, these do not take away from the fact that we had a good stay a Max's place.
thanks for a good stay Max!
