The first thing I must say about Karim was that he was very accommodating and speedy in his response in getting back to me: my husband and I had a last-minute opportunity to go to Paris without our kids and so I was trying to book an apartment the evening before we left. Despite my late request Karim made it work for us, and even got us directions in time.
When we arrived, Karim was friendly and helpful in showing us the apartment and nearby parking. The apartment was small but very clean, with nice big windows. The bedding was clean and the sofa bed comfortable. I recommend this apartment for a young single person or couple wanting an affordable, genuine Parisian experience in an authentic neighborhood (nice cafe across the street for breakfast!).
