My fiance and I stayed here during a quick trip to Paris for my birthday. The host was very nice and accommodating. He met us at the flat to show is around.
The flat itself was nice. The bed is just a simple pullout spring, so not the most comfortable, but it gets the job done. The flat is well decorated and is very modern.
The location was a bit off putting. Very close to city center and easily walkable, but it's not on the safest street so you will hear all sorts of things happening outside if you happen to have the windows open for air. We chose not to walk outside in the evening for this reason.
Overall, it was a great value for what I paid and I would recommend it if you have a tight budget and need a cozy spot to lay your head.
