We had an excellent stay at Stéphane's apartment. It is excellently located -- a small walk from Gare du Nord / the Eurostar terminal, and very close to boulangeries, hire bicycles and cafés.
My top tips to any future travellers would be to plan your hire bicycles in advance, i.e. get a card. Stéphane was helpful in advising us how these work which we really appreciated. The hire cycles are all over Paris and are much cheaper than the other scooters etc.
