Very convenient location, excellent friendly front desk people/service, pretty nice breakfast (juice, bread, butter, croissant, coffee, cereal, jam, etc), has kitchen that you can use at night, room small but adequate, clean, has a small patio/balcony (at least mine did). It has an elevator, which is convenient. The area is walkable and seems to be safe. It gets better and better as you walk towards the center, has many cafes, shops. Close to Gare del'Est and Nord.
Really, the only con was the sound proofing - you could not hear any street noise, but the neighboring bathroom or people walking in the halfway were very clearly heard. Luckily, there were not many of them staying on the same floor, and they were not too late or too early, about the same schedule, as me, so it was ok. I always use ear plugs when traveling anyways.
