Perfect location, walk 10min to the riverside, Louvre, Notre Dame or Jardin du Luxembourg. lots of restaurants, bakeries and shopping close by.
Taxi from Gare du Nord cost us 18€ but Metro no 4 goes direct to Odeon, which is 2min walk to Benoit's apartment.
The apartment is lovely, as described and shown in the layout. Lots of small practical details and feels as if its been fitted out by someone who actually lived there and smoothed out the niggles. Well equipped kitchen. solid wifi.
above all, we would recommend the apartment for Benoit's warm hospitality, air of efficiency and responsiveness which really elevates the experience from good to excellent.
The one thing to be aware of is the spiral stairs to the 2nd floor location without a lift. It didn't deter us with hand luggage/foldable pushchair especially as Benoit helped at checkin but it is something to consider.
