The appartment is as depicted in the pictures, it may not be modern but it has what is needed for a stay in Paris that includes kitchen. We were 3 + a 3 y/o and it went well.
Location-wise it is inside Paris so is good, however is not central so metro or bus is needed to go everywhere...the bus is close and the metro is 7-8 min away.
The hosts were very kind and available for any of our queries and demands, even if we had to leave early on a sunday (5am) they didn't have nay issue to be available. We were happy with the stay.
