The hosts are kind.
The issue is that there are 4 rooms, 3 of which rented through air bnb and this detail is not in the listing’s description.
The photos do not reflect the reality, for example in the photos there was a window and our room did not have a window.
During our experience one room was rented to a family which had a new born baby(crazy to go with a new born baby to a shared flat) so during the night the baby cried waking us up all time.
Moreover, since the fact that there are 4 rooms it is not in the listing’s description we were not aware that we had to share the toilette with other 8 people.
