This is a great little apartment, a perfect pied-a-terre, fitted thoughtfully with everything you're likely to need. It's bright and airy, comfortable and it has a great shower!
It's ideally located for travel from and to Gare du Nord and located on a quiet street. It's close by to the Sacre Coeur and The Moulin Rouge so great for sightseeing in the northern part of the city. The one thing I would suggest bearing in mind is that the area directly outside the nearest metro (Barbes) isn't the friendliest. Obviously you can get this kind of thing anywhere, but if you aren't used to a city atmosphere, I would suggest planning for taxis back rather than the metro, especially if travelling late at night.
We found Veronica (our host) incredibly efficient throughout the booking process and there is a handy guide of local things to do etc. When we arrived, the fridge had been stocked up like a hotel mini bar, which was a really nice touch.
