I liked the proximity to two different Metro lines. The Hostel's location is directly at Sacre Coer. Very handy are the two supermarkets right next door, where you can buy food which you can prepare in the common kitchen.
I stayed in the privat double room, which was clean and perfectly fine for few days. The toilet is also clean and functional, a bit small though. One bad thing, however, is the very low water pressure of the shower.
The staff is friendly and courteous, English, French, Spanish is spoken.
Unfortunately there are no couches or other nice hang out area, where you can relax or get to know other people. I couldn't sit on the terrace, because it was raining.
