The appartment is ok, it's cozy and comfortable, a bit cold though (even with central heating), but it was clean and ok. We spent very little time there, so for what we needed it was ok. We had problems with the check-in as we got to Paris at almost midnight and the Key-safe for the pick up did not work properly, so we spent about an hour trying to figure out how to get the keys.
Airbnb responded well and the Key-safe company did help us out in the end when we could finally reach them.
This key pick-up place is also like 10 min by car from the actual place, so it's not very practical if you arrive late.
Appart from the check-in the rest was ok.
