The location is amazing for sure. The hosts are great and communication is amazing too! Otherwise the place is not totally as in the pictures. Some repairs have been done on the cheap side and there is some potential safety issues (loose cable around the electric box). This can be noisy - there is a background noise (from the heating system) at night: i was not able to sleep the first night but was totally fine with earplugs the nights after.
So depending on what you are looking for that can be a great place or not. This is definitely not the best Airbnb I experienced in Paris but definitely not the worst too! And for sure the location is unbeatable and communication is very great for sure, something to consider if you are here as a tourist!
