Small apartment, but with everything you may need. Very good location! So many metro lines. Close to most places. We went everywhere by walking. Used metro only to get Montparnas building. A lot of small nice shop just around. And most great - brasserie working till 6:00 am, while everything is closed. Very quiet district.
Cendrillon is so lovely person!!! Always in touch. I've lost a key and had new one in just 20 min!!!
