The accommodation is exactly as described, perfect for a couple traveling through Paris. We were only really using the space to sleep in and cook the occasional small meal, if this is what you are after then there is more than enough room.
We found the location easy to walk to from Gare du Nord for the Eurostar. It is certainly walkable (approximately 30mins) to some of the main attractions in the centre of Paris such as Notre Dame and the Louvre, and there is a Metro station a few minutes walk away that served every other attraction not within walking distance such as the Eiffel Tower.
All the staff were exceptional, Michael was very responsive to any queries, as was Josmar who also went out of her way to ensure we felt welcomed and comfortable on our arrival.
Would happily recommend to others!
