Despite a number of unpleasant reviews, we were very pleased with our stay.
The apartment was compact but had everything we needed, and was close to the Eiffel Tower. The host was very responsive and the apartment was nice and warm despite the sub zero temperatures outside.
The sofa bed in the living room did have some slats that had come out but we were able to fix it.
I would highly recommend this Airbnb apartment to friends.
