A very simple addition would make the stay acceptable. The futon bed is horrendous and after all this is bed and breakfast. No breakfast as expected but we did expect a usable bed. We had no need to stay in the room other than somewhere to store our bags and sleep. After sightseeing around Paris you want a decent night's sleep and that is impossible. Our daughter of 12 y o couldn't even manage to use the sofa bed. The main bed up on the mezzanine is average at best. It would be a great place to stay but due to the beds there is no way we would return. We didn't meet the owner it was a key code system which worked fine. There were noisey neighbours on one of our nights of three until 3 a.m. other than that it was very quiet. I would note that it is possible to open the very large window into the room from outside with pliers, it is not totally secure but it seems you'd need to already be in the building to do this via verander access. Line 2 metro doesn't run from Gare Du Nord.
