This is a small place, just fine for one person. Two people would have to like bumping into each other.
Convenience is excellent. Close to the main entrance, on the main floor, three minute walk to the Metro, bakery, grocery store. Twenty minute walk to Sacre Coeur . Two minute walk to a delightful park.
No microwave, coffee machine, or oven, just a hotplate, kettle, and small fridge.
Shower is small. Bathroom sink is too small to wash my (big) hands in.
I stayed for three weeks while on vacation, and found it a quiet, clean place to stay.
