The place is nicely decorated and well located. You are right in the centre of Montmartre and it's a three minute walk to Moulin Rouge and a 20 minute walk to Sacre Cœur. Bus and metro stations as well as the Gare du Nord are very close.
Another big plus: There is a lift.
Unlike many other AirBNBs it is a real inhabitated home including all the owners' personal stuff and even a living fish.
However there were some issues.
The biggest is that we were seven people which we had indicated beforehand, but have only been provided with blankets for five and towels for three! When we asked for more, it took them a while to respond and then they told us to search the whole place for additional towels/blankets. Still, we couldn't find additional ones. Two of us ended up sleeping without blankets!
In addition the shower showed signs of mildew and especially the living room had a strong smell of mildew.
