This apartment is nicely nestled in the 4th arrondissement. Lots of nightlife and restaurants nearby - but far enough away that you don't hear it. It's also close to the Metro, so easy access to all of Paris.
The apartment building has that old world Paris feel and the apartment is on the 5th floor with a pretty, circular winding staircase. Just mentioning as there isn't an elevator - but this adds to the charm.
The bed wasn't terribly comfortable. It's a thin mattress and the bed pillows were also thin. But, there are others on the bed that you can combine together so it's more comfortable.
The only issue we really had was the cups in the bathroom had mold in it and the other glasses were dirty. And, the drain hole is very black but may be typical for old plumbing the building has. Just need to close the toilet lid when you're using the basin so you don't see it.
