This was the perfect situation for my colleague and me for a 1-night last-minute booking in Paris. Easy to get to and from Gare Nord by metro. It would not have been suitable for those who have more traditional expectations, but we loved it. Comfortable sleeping arrangements and perfectly suitable washroom in a lovely, cozy flat. We didn't need the kitchen, but it would have been fine if we had needed it. And plenty of room for all our bags. We had some trouble with the door code, but Gilian responded quickly and all was sorted out.
An unexpected bonus was that it was just 5 minutes walk from Frenchie -- we had an incredible dinner at the wine bar without a booking!
