We had a great time at Caspers apartment. He was friendly and took the time to show us maps and introduce us to the area. He provided a baby bed, highchair and toys for our 10 month old daughter. The place is clean and modern and the bed is very firm. We stayed on a weekend and the street had a lot of people out and about during the night. The neighbourhood is quite diverse and has some good little eateries nearby. The location is good (We walked to the Eiffel Tower, it's a long way but doable) and close to the metro. We had a car and found parking right out the front.
We'd stay again if we are in Paris.
