I stayed for 6 weeks at Jean-Paul and Adre place. Both were very friendly, gave me tips, sometime a piece of cake and a nice talk.
But to be honest, I would not have booked it if the profile was correct, which was not the case - there are multiple errors in the apartment profile.
It says private WC but it is not private since it is shared with all guests that are coming over at their place which happend about 1-2 a week. Also there is a cat, which was not written online and led for me who has allergies to daily medication. Furthermore, it says you can lock the room, which was not possible. That was especially upsetting, when they rented out their apartment to a party of total strangers without letting me know it beforehand.
In the bathroom were used razors.
All in all, it was a okay stay and especially the location is very good if one has eg. to do work in the European district. For a stay of one week recommended - long term not.
