We had a great time staying at Emmanuel's apartment. Communication was easy, friendly and quick, and the apartment was very clean and comfortable. It is also very spacious for Paris!
All the basics are there for the kitchen and the shower was nice to use. It is quiet at night and the bed is firm (French-style!) but comfortable. The included parking spot was a huge bonus for us, and it was really easy to unload and load the car using the lift (great when raining a lot!)
It is 25-30 min by Metro to the main sites/areas, so just something to be aware of - I thought we could walk sometimes, but it is a bit far. The Metro stations are convenient though, as everyone has said. The local area is definitely not touristy but there is a good boulangerie nearby and a few smaller supermarkets. I would definitely recommend the apartment or stay again!
