The apartment is lovely and well furnished. Having the separate sleeping spaces really suited us with teenage children, although the bed on the mezzanine floor would not be suited to anyone with any mobility issues as the steps up to it requires careful negotiation. The shower and bathroom were more than adequate and exceeded expectations.
It was an easy walk from the Gare du Nord, although there are a few streets which feel more oppressive due to the gatherings of young men which you have to walk through to get to the apartment. It’s close to Monmartre and was well situated for the metro into central Paris.
