Despite its name, the apartment is not in the North Marais, but in a neighbouring poor area full of african immigrants; we liked this area a lot, but other people may feel unconfortable or unsafe. The apartment is large for parisian standards, silent, quite clean and well mantained; however there are many ants and the couch is very stained. The apartment is owned by a company renting many places at the same time (which is quite far from the original airbnb spirit), so you will not find anybody welcoming you and being ready to provide help, as it usually happens with a genuine airbnb host. After our booking, the company started sending a thousand of additional rules, menacing high fines if we did not comply. We had no problems in complying with the rules, but we didn't like their attitude. They are not flexible at all on check-out times; we asked for a place where dropping our luggage after check-out, and the only help they were able to provide, was sending us to a private lockers service, more than 1km far from the apartment, that charged us 30 euros for keeping our baggage for a few hours! In many years of airbnb, it is the first time this happens to us: a "true", human airbnb host is always able to propose a good solution.
