I stayed at Boris place with my husband and parents. The place is perfect for two couples. It's comfortable and clean. I really liked the neighborhood, Montparnasse. It's full of energy but not touristic. It's close to many great restaurants and cafés which we enjoyed for a couple nights. It's also walking distance to a popular restaurant called Josephine Chez Duomonet. 2min walk to Metro.
Boris is a fantastic host. He answered my questions through texts, recommended restaurants, brought over anything missing from the house, and gave us good info about Paris.
Enjoy Paris and stay at this great apartment.
