The unit is exactly as listed.
Communication with host was excellent and the unit was very clean.
Please note it is a cozy unit somewhat small but I suppose expected in Paris.
The bed is on the upper level with limited ceiling height approx 4 ft. so maybe a challenge for some older travellers although a unique experience. The train ( RER B ) was very close and can bring you other stations.
Easily walkable to many sites, bars , restaurants, etc.
Overall I would stay again.
