We had a nice stay, the apartment was clean and just like in the pictures, except some decoration but that is not important. We were welcomed by Léonor who explained the things to us and was very responsive to our questions during our visit.
It is in a lively neighbourhood with a couple of grocery stores nearby and restaurants. It's a great place to stay when discovering Paris because the metro station Jourdain is just 5 minutes away and the bus station L'Ermitage about 2 minutes. The apartment has all amenities you would need, tv, fridge, microwave oven, washmachine, waterboiler, coffemaker etc., the bed is comfortable... we didn't miss anything. I think the place can be very warm in the summer because it is on the top floor of the building. There is no elevator and the stairs are narrow so if there is a way, avoid bulky luggage because you will have a hard time getting it up to the 5th floor.
We would stay here if we were to visit Paris again.
PS: Ask for the instructions to the hot water because it's tricky (but also simple) if you never have seen something like that.
