The location is absolutely fantastic and within walking distance to all big must sees!
Rooms are comfortable, but like most hotel rooms in central Paris they are SMALL: Getting from you bed to the toilet turns out being like a walk I a labyrinth, literally criss-crossing between bed, tables and chairs, and as the hotel is located in a busy road in a restaurant/bar area, some noise may be expected.
Paying 15 Euro for breakfast, you could expect more than their VERY basic version!
Staff is nice but not smiling and helpful, keeping up the French arrogant distance.
