We had a very good time at this Air BnB. First of all, the communication was perfect. They contacted us as soon as we booked the bnb and sent us the information soon enough how go check-in etc. They also send you kind of an paris-introduction booklet which is very kind!
The room itself is made for two to max three persons - it is not very big but enough for a weekend trip to paris!
It was clean all in all - only the kitchen items and the floor were not very clean. The rest was perfect!
The air bnb is situated in the centre of paris - what do you need more?
I can highly recommend you this place:)
